Full textThe reliability control of critical electronic components is one of the challenges to be faced by railway stakeholders. IGBT (Insulated Gate Bipolar Transistors) power modules belong to this list of components. They are subject to high stresses corresponding to those encountered in harsh railway environments. The environmental conditions encountered in rail operations and the demanding availability requirements impose high levels of reliability on IGBT. In order to improve their reliability, an evaluation methodology has been developed based on a probabilistic approach and supported by a Bayesian network. For the implementation of the model, several working elements were assembled. First, an original approach called "U-Cycle" was proposed, highlighting in a one-to-one way a system level associated with the train and a component level similar to the IGBT considered simultaneously according to functional and dysfunctional views. In this context, the work led, first, to highlight the mechanisms characterizing, in a top-down logic, the influence of train loading on component stress and, in a bottom-up logic, the dysfunctional impact of the failure at component level on system reliability. In a second step, the results of this analysis led to the implementation of the structure of a Bayesian model whose generic nature allows it to be deployed for the reliable modelling of any type of rail system. The modelling work based on Bayesian networks is used to support the reconciliation between analytical models (failure physics) and data from the use of the elementary component in its operating environment. The model was used to model the reliability of an IGBT in an application framework corresponding to the metro in the city of Chennai, India. The data and expert knowledge collected on the project made it possible to determine the probability tables of the Bayesian network. The probabilistic results of the model have been translated into reliability indicators

Full textThe supply of carbon-free energy is possible with renewable energy. However, windfarms and solar power plants are geographically away from the distribution points. Transporting the energy using the HVDC (High Voltage Direct Current) technology allow for a better yield along the distance and result in a cost effective approach compared to HVAC (High Voltage Alternative Current) lines. Thus, there is a need of high voltage power converters using power electronics. Recent development on wide bandgap semiconductors, especially silicon carbide (SiC) allow a higher blocking voltage (around 10 kV) that would simplify the design of such power electronic converters. On the other hand, the development on packaging technologies needs to follow this trend. In this thesis, an exploration of technological and normative limitation has been done for a high voltage power module design. The main hot spot are clearly identified and innovative solutions are studied to provide a proper response with a low impact on parasitic parameters. Partial Discharges (PD) on ceramic substrates is analyzed and a solution of a high Partial Discharge Inception Voltage (PDIV) is given based on geometrical parameters. The XHP-3 like power modules are studied and a solution allowing a use under 10 kV at a high pollution degree (PD3) is given

Full textThe domain of power electronics reliability has become an important center of interest with the recent massive system electrification. The manufacturers are more and more confronted to the necessity of producing reliable devices with optimized maintenance. Electronics components, such as IGBTs, diodes and MOSFETs assembled in power modules, are at the center of the systems conversion, and as a consequence, are subjected to high environmental and functional stresses (ambient temperature, vibrations…). All these factors have a strong impact on the components lifetime and thus on the devices reliability. Economically, scheduling a maintenance with a system replacement is less detrimental than a brutal failure of the system. As a consequence, the use of lifetime prognostic tools is necessary. The problematic consists in the health state prediction of power modules in functioning to be able to schedule a maintenance before the failure of the equipment.To be able to determine the remaining useful lifetime of power modules in functioning, lifetime models are used. These models can either be empirical, physical or statistical. The empirical models are the most common ones, because of their easy establishment and implementation. They are based on results from accelerated power cycling tests, which reproduce the stresses endured by the power modules in severe conditions. An extrapolation is then needed to obtain the power module health state in normal functioning conditions. The main drawback of these models is the lack of description of the physical mechanisms leading to damage, resulting potentially in errors in particular during extrapolation. That’s the reason why physical models start to draw more attention.In the thesis, two physical lifetime models of IGBT power modules are proposed. The first approach is based on deformation induced inside the device assembly in operation. The degradation is in this case described by the quantification of deformation related to thermal stresses. In the second approach, the lifetime model is based directly on damage through the establishment of a degradation model. These two lifetime models are finally compared to show the benefits and disadvantages of each. More generally, the establishment and comparison of these models is part of an approach to develop diagnostic tools so that the remaining useful lifetime of power modules can be predicted in operation

Full textThe major failure mode of power IGBT modules is thermo-mechanical fatigue. Thermal heating leads to mechanical stress due to the difference in the coefficients of thermal expansion of the materials involved. How long they last, which is linked to dissipated inelastic energy, strongly depends on the nonlinear behaviour of materials. The interest of this work lies in the application of traditional reliability methods to the field of power electronics. We first introduce the different stochastic methods, taking into account the random behaviour of the model's data. Modelisation, used to define the limit state surface, is made of the different failure modes of power module. We present here an original strategy of finite element modelisation. Since failure is assessed by material behaviour, we identify the Sn/Ag3. 5 solder nonlinear law with relaxation and work-hardening test. An adaptive surface response method with parallel computing is implemented and applied on several reliability studies : electrical, thermal and mechanical

Full textIn railway applications, the increase of the power density leads to the development of more and more integrated inverters. This integration is only possible if each component has its own well-established design rule. Regarding the insulating materials, a wide characterisation of the different materials ensuring the packaging functions is all the more necessary that it may lead to a better understanding of their failure mechanisms. This last point will become crucial if the actual trend (decrease of the module size and increase of the component voltage level) is extended. Electrical stress grading inside the module appears therefore as a key issue to ensure the integrity of the systems. This work is a contribution to stress grading effect and different solutions are examined in details. Among others, we focus particularly on hybrid materials and floating potential conductive lines. Various tools are used and developed both from a theoretical and from a practical point of view to achieve this characterization. Finite Element Method (FEM) is used to predict the stress distribution in the structure under study. Materials presenting non-linear I(V) characteristics are characterised and their results are discussed in details. Alternative methods are also proposed to characterise them directly through the measurement of the potential distribution (thanks to a Kelvin probe) and indirectly via Partial Discharge measurements. Then, a stress grading method using floating potential conductive lines inspired by guard rings and field limiting plates is proposed. An optimisation of the structure thanks to FEM method and through a dielectric characterisation using partial discharge and dielectric strength measurements is achieved

Full textThe increased demand of offshore power conversion systems is driven by newly initiated offshore projects for wind farms and oil production. Because of long distances to shore and inaccessibility of the equipment long repair times must be expected. At the same time the offshore environment is extremely harsh. Thus, high reliability is required for the converters and it is important to have good knowledge of the switching devices. This thesis investigates switching characteristics and losses of commercially available IGBT modules to be used for this application. It focuses on switching time and switching energy losses depending on gate resistance, current and voltage levels, operation temperatures, and show differences between several devices of the same type. Some test show how device characteristics and losses when the device has been exposed to stress over a certain period.

Full textThis thesis deals with the Modular Multilevel Converter M2C, an emerging and highly attractive multilevel converter topology for medium and high voltage applications. One of the most significant benefits of the M2C is its modular structure - the converter is composed of six converter arms, where each arm consists of a series connection of identical submodules (cells) and an inductor. Thus, the number of distinct voltage levels available for the line-to-line voltages is proportional to the number of submodules, which is in principle arbitrary. For the investigation of this complex converter topology, two simulation models - a continuous model and a discrete model - are derived. For this purpose, the electrical circuit is described by a system of ordinary differential equations where the switching states of the power semiconductors are represented by the so-called switching functions. The continuous model results from the analytical solution of the differential equations with a continuous interpretation of the switching functions. In contrast, the discrete model uses discrete switching functions and is computed using numeric integration methods with MATLAB/Plecs. One aspect of particular significance with the M2C is the topic of inner currents: the so-called circulating currents. In this thesis, these current components are defined mathematically in the time domain for the first time and the harmonics of the circulating currents for symmetrical operation of the converter are derived. For the discrete model, closed-loop control of the arm currents is implemented. Initial values for the inductors and capacitors are derived using the analytical equations of the continuous model. The M2C has several distributed energy storage elements: the submodule capacitors. The stored energy must be distributed evenly amongst these capacitors. To achieve this, three methods of energy distribution are presented. Another focus of this investigation is the current sharing between the upper and lower power semiconductor within the submodules. For different load phase angles and circulating currents, the current distribution is depicted. The influence of the floating capacitor voltages on the line-to-line voltages as well as the of number of discrete voltage levels in the line-to-line voltages are investigated with the discrete model. The accuracy of the simulation models is verified by experimentation with a prototype of the M2C from the company Siemens. The experimental results are compared with simulation results from the two simulation models. The dimensioning of the power components of the elecrical circuit is divided into two parts: the first for the submodule capacitors and the second for the power semiconductors. Initially, the capacitance of the submodule capacitors are minimized by an iterative algorithm on the basis of three different capacitor specifications. This computation is done using the continuous converter model for converter operation neglecting circulating currents and with optimized circulating currents. In the next step, the power semiconductors are dimensioned using the discrete model and assuming a defined current factor, which describes the ideal parallel connection of several semiconductors. The losses, the loss distribution, and the junction temperatures in the power semiconductors for different load phase angles describe the behavior of the converter for different operating points

For these applications, security is a critical point, thus the reliability of the power assembly must be optimized. The knowledge of time to failure is very important information for the designers of these systems. Inthis context, an early failure indicator would predict system failuresbefore it becomes effective. In this thesis, we focused on the electromechanical characterization of power transistors: MOSFET and IGBT. Based on these results this electromechanical characterization should help us in the longer term, to highlight an early failure indicator of the power assembly

Full textThis thesis is dedicated to reliability investigations led on three-phase 200~A~--~600~V IGBT power modules, designed for building drive inverters for hybrid or electric automotive traction applications. The objective was to evaluate the durability of the studied modules when they withstand power cycling in high temperature environments, and especially their resistance to thermo-mechanical fatigue. Two complementary approaches were considered: accelerated aging experiments and numerical modeling.A series of power cycling tests was carried out over a large range of temperature profiles, defined by the ambient temperature and IGBT junction temperature excursion. These quantities are used as thermal stress acceleration factors. Those experiments were led in realistic electrical conditions (PWM control scheme). They aimed at identifying the failure modes of the target devices, assessing the impact of the acceleration factors on their aging process, and evaluating the suitability of standard aging indicators as damage precursors in such harsh loading conditions. Besides, to better understand the failure mechanisms governing the fatigue life of the modules assembly, a thermo-mechanical modeling focusing on solder joints was built. Our simulation efforts concentrated on the appraisal of constitutive modeling effects on solder joints lifetime estimation. Numerical analysis of the assembly response to power cycling in similar operating conditions as practiced in experiments were performed. Behavior laws were then compared on stress, plastic strain, and strain energy density developed within the joints

Full textIn the case of photovoltaic installations, the DC/AC inverter has the highest failure rate, and the anticipation of its breakdowns is still difficult, while few studies have been done on the reliability of this type of inverter. The aim of this PhD is to propose tools and methods to study the ageing of power modules in this type of application, by focusing on ageing phenomena related to thermo-mechanical aspects. As a general rule, the accelerated ageing of power modules is carried out under aggravated conditions of current (Active Cycling) or temperature (Passive Cycling) in order to accelerate the ageing process. Unfortunately, when applying this type of accelerated ageing tests, some failure mechanisms that do not occur in the real application could be observed, while inversely, other mechanisms that usually occur could not be recreated. The first part of the PhD focuses on the implementation of an accelerated ageing method of the semiconductor devices inside photovoltaic inverters. This is accomplished by analyzing the mission profiles of the inverter’s output current and ambient temperature, extracted over several years from photovoltaic power plants located in the south of France. These profiles are used to study photovoltaic current dynamics, and are introduced into numerical models to estimate losses and junction temperature variations of semiconductors used in inverters, using the cycle counting algorithm “Rainflow”. This method is then performed in two experimental test benches. In the first one, the devices under test are IGBT modules, where the accelerated ageing profile designed is implemented using the opposition method. Moreover, an in-situ setup for monitoring ageing indicators (thermal impedance and dynamic resistance) is also proposed and evaluated. The second bench is devoted to study the ageing of SiC MOSFET power modules. The accelerated ageing test is carried out under the same conditions as for the IGBT modules with more monitored electrical indicators, but this time by disconnecting the semiconductor devices from the inverter. The results obtained allowed to determine several potential ageing indicators of IGBTs and SiC MOSFETs used in a photovoltaic inverter

Full textThe recent use of the hybrid integration technology of high power IGBT modules in traction applications instead of the classically used presspacked thyristors or GTOs introduced new questions conceming the reliability of the modules' packaging when subjected to the traction thermal cycles. The aim of this thesis is to contribute to understand the failure mechanisms of IGBT modules in traction environment. Therefore, a good knowledge of the aging accelerators and the failure indicators is indispensable. The long term goal of the study is to help to find a law expressi11g the modules life time as a function of their working conditions. To treat the problem, we chose an experimental approach consisting in power cycling accelerated tests and technological and failure analysis. We validated a contact temperature measurement method on silicon chips surface which was used to localize and evaluate the highest thernial stress in power cycling conditions. These measurements made it possible to evaluate a thermal model of the modules packaging using LAASTHERM software. A local thermomechanical modeling of the modules with the finite element method was also achieved and provided the mechanical stress in the weakest interfaces of the packaging. We finally proposed an empirical aging model but we didn't get enough experimental data to validate it

This has required the development of an active cycling test bench for the characterization of the thermal tiredness of IGBT modules, the analysis of the degradations generated in their assembly, and the classification of their operating mode : in " healthy " mode and " degraded " mode. The strategy adopted for the thermal cycling, aims to reproduce the constraints imposed on the components during their real operation. We followed the module static and dynamic parameters in order to detect possible drifts, and thermoelectric parameters used as criteria of thermo-mechanical degradations in their assembly. The thermal stress caused mainly, earlier switching-on and switching-off modes and appearance of a tile-current. A failure analysis has revealed, in the component assembly, bond-wire lift-off, solder layer degradation, and surface dislocation of the gate and emitter metallizations. The implemented SVM classifier, allows to distinguish between an IGBT degraded operating mode and a healthy operating mode, for a preventive maintenance in electric installations where the continuity of service and safety are very important

Full textIGBT transistors are the most used power semiconductor devices in power electronics and are often integrated in power modules to constitute basic switching functions. In various applications, IGBT power modules suffer thermal cycling (or power cycling) due to variations of operating conditions. This power cycling induces thermo mechanical stress that can lead to damages and then, to failures. Ageing tests are a means to identify and analyze the degradation mechanisms due to power cycling by imposing calibrated test conditions. In addition, their results can be used to establish empiric lifetime models that are useful for power converter designers.The present work describes the implementation of an ageing test method dedicated to IGBT modules operating in the 600V-200A range. This method takes advantage of particular operating conditions generated by pulse width modulation inverters in which the IGBT modules to be tested are introduced. The modulation induces a variation of IGBT die temperature, i.e. a power cycling, of which the frequency is significantly higher (2Hz to 10Hz) than the operating frequencies of classical test systems. By using this technique, the test length is reduced while low values of thermal amplitude can be reached.Throughout the ageing tests, the monitoring of ageing indicators is required to evaluate the sample health and to stop the operation when predefined conditions are reached. In the present work, the ageing indicator is the on-state voltage VCE across the IGBT device that is relevant in regard with wire bond degradations. Therefore, as a complement of the fast test method, an automated VCE monitoring system has been developed in order to fully take benefit of the high test-speed. In addition, this system is able to measure the junction temperature and to provide the temperature profile during the power cycling.This test bench has made possible the ageing process of three dozen of samples by applying thermal swing amplitudes in the 30°C-50°C range, that is not reachable with classical test benches operating in low frequency because of the unacceptable test length. The results show that only one kind of damage is generated by the present test conditions, i.e. the degradation of attaches between the emitter metallization and the wire bonds. In many case, complete lift-off have been observed. Some samples have been used to evaluate the influence of thermal swing frequency on the results. The latter are unchanged when the frequency varies between 2Hz and 0.2Hz, therefore it is a first validation of the fast test relevance

Full textCurrently, the standard 2D hybrid power module (power converter) is the reference technology for the medium and high power market. This hybrid power module is a discrete multi-chip case. The semi-conductor chips are interconnected by wire-bonding to form switching cells. The wire-bonding interconnection technology is a limiting factor in terms of electrical and thermomechanical performances, three-dimensional integrability and productivity. The aim of this thesis is to study new architectures of very integrated power converters. Compared to the so-called hybrid reference technology, the proposed architectures aim at a greater degree of integration, with an integration at both the semi-conductor level (monolithic integration) and the packaging level (hybrid integration). Monolithic integration consists in integrating switching cells into new multi-terminal macro-chip architectures. Hybrid integration consists in developing of new technologies to assemble these macro-chips. To validate the different proposed integration architectures, the first step was to study and validate the operating modes of the new chips by SentaurusTM TCAD simulations. Then, the multi-terminal chips were realized in the micro and nanotechnology platform of LAAS-CNRS laboratory. Finally, the chips were bonded on PCB substrates to realize power converter circuit prototypes. The highly integrated switching loop presents a stray inductance loop lower than one nanohenry, wich is an important improvement as compared to the values reported in literature (about 20 nH)

Full textAinsi, la première partie de cette thèse présente les tests expérimentaux réalisés en cyclage actif durant lesquels nous avons cherché à évaluer la tenue des modules IGBT (600V-200A) fonctionnant à différentes températures ambiantes (température de semelle) et différentes températures de jonction (température des puces). Afin de chercher à comprendre les mécanismes physiques mis en jeu dans la dégradation de l'assemblage, les essais ont été arrêtés rapidement dès lors qu'un indicateur de défaillance laissait supposer une initiation de processus de dégradation.
Dans la deuxième partie, nous nous sommes focalisés sur la tenue des brasures substrat/semelle dans des conditions de cycles thermiques passifs. Sachant qu'habituellement le facteur d'accélération retenu pour le vieillissement de ces brasures est l'amplitude des cycles thermiques, nous avons cherché dans cette partie à évaluer non seulement l'effet de l'amplitude des cycles thermiques mais aussi les niveaux des paliers haut et bas sur l'initiation des fissures dans ces brasures et leurs propagation au cours du cyclage.
Enfin, pour comprendre et analyser le comportement de la brasure et de l'assemblage sous les contraintes de cycles thermiques, une étude par simulation numérique est présentée dans la dernière partie. Une étude numérique effectuée sous des conditions de température similaires à celles imposées dans la partie expérimentale a permis de localiser et d'évaluer les contraintes thermomécaniques que subissent les éléments de l'assemblage. Surtout, nous donnons des éléments de réponse permettant d'établir un lien entre les paramètres thermiques du cyclage passif et les grandeurs physiques qui sont influent sur la durée de vie des brasures. Enfin, cette partie se termine sur une étude numérique dans laquelle nous avons cherché à simuler l'effet combiné des cyclages actifs et passifs sur les contraintes mécaniques au sein des modules IGBT afin de rendre compte des contraintes imposées aux modules dans une application réelle.

Full textThe thesis deals with a detailed comparison of voltage source converter topologies with a central dc-link energy storage device for medium voltage applications. The Three-Level Neutral Point Clamped Voltage Source Converter (3L-NPC VSC) is compared with multilevel Flying Capacitor (FLC) and Stacked Multicell (SMC) Voltage Source Converters (VSC) for output voltages of 2.3 kV, 4.16 kV and 6.6 kV by using state-of-the-art 6.5 kV, 3.3 kV, 4.5 kV and 1.7kV IGBTs. The fundamental functionality of the investigated converter topologies as well as the design of the power semiconductors and of the energy storage devices (Flying Capacitors and Dc-Link capacitors) is described. The installed switch power, converter losses, the semiconductor loss distribution, modulation strategies and the harmonic spectra are compared in detail

Full textMedical imaging systems, mainly X-rays imaging systems, have become essential in the diagnosis and treatment of complex diseases. X-rays generator is one of the critical subsystems of a medical system. Its technology became more complex and constraints seen by the components increase. An assessment of X-rays generator reliability is therefore necessary to optimize its lifetime. In this thesis, a reliability assessment method of an X-rays generator is proposed. The methodology is based on the assessment of the reliability from component to system. Aging tests are first performed for X-rays generator critical components in order to identify failure mechanisms and build lifetime curves for performing reliability prediction. FIDES guide parameters were also used to construct critical components lifetime curves. A reliability prediction method based on the assumption of cumulative damage with Miner's rule is proposed to evaluate critical components lifetime under thermomechanical stresses. This method uses rainflow counting rules for the temperature cycles distribution of critical components. A reliability block diagram is finally used to estimate the lifetime of each X-ray generator subsystem through its critical components
