Abstract:
Abstract The main advantages of multiphase interleaved DC-DC converters over single-phase converters are reduced current stress and reduced output current ripple. Nevertheless, inductor current ripple cannot be reduced only by an interleaving method. The integrated magnetic structure can be used to solve this problem. In this paper, the application of 2-phase coupled inductor designed in a convenient way by using commercially manufactured coil formers and ferrite cores is analysed to develop a 4-phase interleaved DC-DC converter. The steady state phase and output current ripple in a boost mode of the interleaved bidirectional DC-DC converter with integrated magnetics are analysed. The prototype of the converter has been built. The experimental results of the current ripple are presented in the paper.

Abstract:
A photovoltaic (PV) generator exhibits nonlinear voltage-current characteristics and its maximum power point varies with solar radiation. Analytical investigations of the new family of switching converters based on a parallel connection of (=4) identical buck-boost converters employed in PV system are presented. The interleaving strategy ensures that all the converters operate at the same switching frequency. Mathematical models developed using the state-space average technique are presented in this paper. Various steady-state performance expressions are also derived. The present converter system has the advantages of reduced size of the converter, and ripple in the total inductor current. The effectiveness of the four-phase interleaved dc-dc converter combined with PV system is demonstrated through simulations carried out in MATLAB environment.

Abstract:
This paper represents a design and implementation of a digital control of variable frequency interleaved DC-DC converter using a digital signal processor (DSP). The digital PWM generation, current and voltage sensing, user interface and the new period and pulse width value calculation with DSP STM32F407VGT6 are considered. Typically, the multiphase interleaved DC - DC converters require a current control loop in each phase to avoid imbalanced current between phases. This increases system costs and control complexity. In this paper the converter which operates in discontinuous conduction mode is designed in order to reduce costs and remove the current control loop in each phase. High current ripples associated with this mode operation are then alleviated by interleaving. Pulse width modulation (PWM) is one of the most conventional modulation techniques for switching DC - DC converters. It compares the error signal with the sawtooth wave to generate the control pulse. This paper shows how six PWM signals phase-shifted by 60 degrees can be generated from calculated values. To ensure that the measured values do not contain disturbances and in order to improve the system stability the digital signal is filtered. The analog to digital converter's (ADC) sampling time must not coincide with the power transistor's switching time, therefore the sampling time must be calculated correctly as well. Digital control of the DC-DC converter makes it easy and quickly to configure. It is possible for this device to communicate with other devices in a simple way, to realize data input by using buttons and keyboard, and to display information on LED, LCD displays, etc.

Abstract:
<span>This paper presents the simulation design of dc/dc interleaved boost converter with zero-voltage switching (ZVS). By employin the interleaved structure, the input current stresses to switching devices were reduced and this signified to a switching conduction loss reduction. All the parameters had been calculated theoretically. The proposed converter circuit was simulated by using MATLAB/Simulink and PSpice software programmes. The converter circuit model, with specifications of output power of 200 W, input voltage range from 10~60 V, and operates at 100 kHz switching frequency was simulated to validate the designed parameters. The results showed that the main switches of the model converter circuit achieved ZVS conditions during the interleaving operation. Consequently, the switching losses in the main switching devices were reduced. Thus, the proposed converter circuit model offers advantages of input current stress and switching loss reductions. Hence, based on the designed parameters and results, the converter model can be extended for hardware implementation.</span>

Abstract The authors present the control principle of the multiphase interleaved DC-DC converter that can be used to vastly reduce output current ripple of the converter. The control algorithm can be easily implemented by using microcontroller without current loop in each phase. The converter works in discontinuous conduction mode (DCM) but close to boundary conduction mode (BCM). The DC-DC converter with such a control algorithm is useful in applications that do not require precise current adjustment. The prototype of the converter has been built. The experimental results of the current ripple are presented in the paper.

Abstract:
<p>The continuously increasing demand for control on electric power equipment has led to the rapid technological development in various applications such as renewable energy, electric drives, and communication. Pulse Width Modulation (PWM) switching is an important technique to control the output voltage. PWM signals can either be generated using digital controller or analog controller. Digital controllers are widely used to generate PWM signals due to their reliability in solving complex algorithms within short amount of time. Multiphase boost converter is capable to overcome high input current ripple, current stress and semiconductor losses in conventional boost converter. This paper proposes a PWM switching scheme for multiphase interleaved converter using Field Programmable Gate Array (FPGA). The proposed switching scheme uses PWM switching technique that is implemented by programming Altera DE2-70 board. The duty cycle can be easily adjusted using assigned switches on the Altera board. For validation, switching frequency was set to 100 kHz, and then switching signal was observed using oscilloscope.</p>

Abstract:
Lithium-ion batteries play an important role in large-scale energy storage systems. However, the power inconsistency of the battery packs restricts the developments of modern technologies in energy storage area. The motivation of the present study is to serve the growing needs of the energy balance for lithium-ion battery packs. The present study proposes a flexible multiphase interleaved converter for the energy equalization of a lithium battery pack with series configuration. Moreover, the graph theory is applied to the analysis of equalization circuits. It is intended to establish a unified standard for the comparison. The parameter of average efficiency is considered as an important indicator to evaluate the characteristics of the equilibrium system. The proposed method is verified by constructing a lithium-ion battery pack with the equalization circuit. It is observed that the proposed multiphase interleaved converter has flexible characteristics, while it has low energy loss compared with the conventional methods. It is found that the proposed method simplifies the complex equalization circuits into graphs and facilitates the comparison of the average efficiency of the system. It is concluded that this method is a feasible and powerful method for evaluating the battery equalization circuit. This approach can be applied for solving complex problems in other engineering applications.

Abstract:
in electric vehicle (ev) systems, bi-directional dc-dc converters are used to interface the rechargeable energy storage system (ress) such as the battery bank with the high voltage dc-link of the inverter. currently multi-cell batteries used in automotive systems, such as ev or hev, are subject to a higher failure rate than single cell batteries. the more cells are used in series, the greater the opportunities to fail and the worse the reliability. when a cell has failed the entire string or even worse the battery must be replaced, which is extremely costly [1]. so, to have less cells in series increases the reliability of the system, which also leads to a lower voltage of the dc link. for this reason and many others, in a hybrid or electric vehicle powertrain, a boost dc-dc converter enables optimization of the battery system. this work aims to investigate all the benefits that come with interleaving technique in dc-dc converters for automotive systems. indeed, these kind of converters for use in high-performance and high-power applications have received increasing interest in recent years. in particular this research work, done with sevcon ltd focuses on the theory behind bi-directional multiphase interleaved (imc) converter and how it could be used to interface a rechargeable energy storage system (ress) to the powertrain of a hybrid or electric vehicle. more specifically, it was investigated if it is possible to use (after appropriate hardware and software amendments) a standard three phase ac motor inverter as a multiphase interleaved converter. for this purpose two motor controller, produced by sevcon have been analysed. both the gen4 size 10 and the hvlp inverters were considered for use as a dc-dc converter. the voltage can step up or down based on the power flow direction. each phase is indeed a bi-directional buck or boost converter, which is composed of a bridge of power switches and inductor.

Abstract:
The power requirements for microprocessors have been increasing per Moore's Law. According to International Technology Roadmap (ITRS), Voltage Regulator Module (VRM) for microprocessors will be about 200 W at 1 V output in 2010. With the VRM’s topology of synchronous buck, serious technical challenges such as small duty cycle, high switching frequencies, and higher current demands, contribute to decreased power density and increased cost. This thesis proposes a Continuous Input Current Multiphase Interleaved Buck topology to solve the technical challenges of powering future microprocessors. This new topology is aimed to improve past topologies by providing continuous input current and improved efficiency. An open loop system of the proposed new topology is simulated using OrCAD PSpice to evaluate the performance criteria of the VRM. A hardware prototype of a four-phase Continuous Input Current Multiphase Interleaved Buck Converter is constructed and tested to assess the targeted improvements.

Abstract:
The growing demands for electrical capacity on future more electric aircraft (MEA) has led the engine-based generators to increase in size. Many manufacturers and researchers have a strong interest in developing fuel cells for aerospace applications due to their advantage of high efficiency and their use as a medium for clean energy resources. A particular interest is in using fuel cells within the Auxiliary Power Unit (APU) - a function that is currently provided by an additional gas turbine in most aircraft. Their integration into aircraft systems is not straightforward. A particular challenge, which this thesis addresses, is the provision of a suitable power conversion system which is able to interface the fuel cell to the aircraft electrical system – taking account of the complex electrical characteristics of the fuel cell and the demanding requirements of the aircraft electrical network. The interleaved boost converter with coupled inductors (IBCI) is one of the many converters that is promising for fuel cell applications because it has low input current ripple and a high step-up voltage gain. It comprises a current doubler circuit, voltage doubler rectifier, coupled inductor and active clamp. The proposed converter is an extended version of the single phase to multiphase IBCI converter using interleaving techniques. The input stage of the converter is a coupled inductor which connected to a half-bridge configuration and an active clamp. The output side is a voltage doubler rectifier. A detailed analysis of the converter and associated modelling are presented. The design and construction of a prototype converter is presented with a particular focus on ensuring operability of the converter over the entire fuel cell characteristic range as well as achieving high efficiency at nominal load. A laboratory-scale (1/10) prototype of a nominal full-scale converter was built to verify the feasibility of the proposed converter topology. Good agreement between the experimental results and the simulation results has been demonstrated, which validates the converter design, modelling, and effectiveness of the efficiency evaluation approximations.

Abstract:
This Thesis addressed the challenge of ensuring balanced currents in the phases of a multi-kW, interleaved dc-dc converter by means of closed-loop digital control. The Thesis examines uniformly-sampled, valley-current, peak-current and average-current control for a dual interleaved boost converter with inter-phase transformer which might form part of the power train of an electric vehicle. Also, an enhancement of the average-current control is investigated in which the transistor duty-ratio is updated more rapidly, which allows an improvement of approximately ten times in the response speed of the system. Based on the theoretical analysis, the average-current control methodology was determined to be the most suitable technique for this type of converter as it ensures well-balanced phase currents over a wide range. To provide a basis for control system analysis and design for interleaved converters, a modelling methodology is developed based on a combination of multi-rate data-sampled theory and a small-signal averaged converter model. The model is shown to represent accurately the interaction between the interleaved phases, revealing a reduced stability range compared with a non-interleaved converter. The modelling and control methods are validated using switched and average value simulations obtained with the SABER software and by experimental results from a 25 kW, 30 kHz converter prototype. The control techniques were implemented on a Texas Instruments TMS320F28335 digital signal controller.

Abstract:
Le domaine de la conversion d’énergie requiert, la plupart du temps, la mise en œuvre d’études spécifiques et coûteuses pour répondre, avec les meilleures performances possibles (rendement, compacité, CEM), aux diverses applications. Afin de proposer une solution générique et évolutive, nous nous sommes intéressés à l’utilisation d’un réseau de micro-convertisseurs optimisés, de faible puissance, que l’on peut associer en série et/ou en parallèle, pour couvrir un large domaine d’applications. Dans ces conditions, un effort unique de réflexion est à porter sur le dimensionnement d’un micro-convertisseur optimisé qui joue le rôle de cellule élémentaire ou de brique de base pour l’établissement du réseau complet. Cependant, cela suppose de mettre en œuvre également une méthode de contrôle adaptée au grand nombre de micro-convertisseurs ainsi qu’une technique de communication entre tous les micro-convertisseurs, pour assurer un bon équilibrage de la puissance. L'objectif principal de cette thèse est de fournir une solution intégrée pour le contrôle à la fois des cellules de commutation internes du micro-convertisseur et du réseau lui-même. Pour y parvenir, une solution modulaire de contrôle entièrement décentralisé est proposée. Trois étapes essentielles sont alors étudiées : la génération des porteuses entrelacées, l’équilibrage des courants de phase et la régulation des grandeurs de sortie courant et/ou tension. Ces trois étapes sont abordées de manière à proposer une solution entièrement décentralisée. Plusieurs cartes de test ont été réalisées pour valider chaque fonction indépendamment. Un circuit intégré (démonstrateur), implémentant l’ensemble des fonctions nécessaires au contrôle d’un micro-convertisseur 5V-2A-1MHz, a également été conçu et testé. Les résultats expérimentaux montrent clairement la validité des solutions proposées, ce qui ouvre la voie vers un contrôle mieux adapté aux nouveaux types d’architectures multi-phasées et distribuées en réseau.

Abstract:
In this work, a modified boost converter design has been implemented in a multiphase configuration with a condensed topology. The modified aspect of the design has already been proven to drastically reduce input current ripple by about 40% in a single-phase implementation. By placing two modified boost converters in parallel with interleaving main switches (multiphase), the input inductors and modified capacitors of the modified topology can be reduced to just one of each, lowering the number of components, size, and cost. Additionally, multiphase DC/DC converters lower input/output voltage and current ripples while delivering more power compared to single-phase converters. By combining the modified and multiphase benefits, this thesis creates a topology with low ripple and noise while providing high power capability. This thesis covers the analysis, simulation, hardware implementation, and testing of the Modified-Multiphase Boost Converter as well as an equivalent Standard-Multiphase Boost Converter for comparison. Simulation and hardware test results exhibited a 9% input current ripple reduction with the Modified-Multiphase design, presenting a high-power converter with considerable input noise reduction.

Abstract:
L'apparition de convertisseurs multicellulaires parallèles entrelacés et magnétiquement couplés a conduit ces dernières années à améliorer les performances des convertisseurs (en termes de densité de puissance, d'efficacité, de dynamique,...). Le pendant de ces améliorations successives résulte en une nécessité d'équilibrage précis des courants de phase, ce qui entraîne une complexification de la commande des ces convertisseurs. Une première étape de détermination de la fonction de transfert d'une boucle d'équilibrage des courants nous permet de déterminer la nature des correcteurs d'équilibrage de ces courants. Cette étude nous permet d'appréhender des systèmes plus complexes avec différentes topologies de couplage magnétique entre les bras du convertisseur parallèle. Suite à une étude bibliographique mettant en avant le manque de précision des techniques actuelles de mesure des courants de bras, nous proposons une technique d'émulation analogique précise de ces courants ne nécessitant qu'un seul capteur. Deux prototypes ont été réalisés et permettent de valider cette technique. Enfin, face à l'intérêt grandissant que portent les industriels pour des architectures modulaires, deux innovations permettant de s'affranchir d'un circuit spécifique de supervision sont proposées. Dans un premier temps, une technique modulaire d'équilibrage des courants est proposée et validée expérimentalement : elle permet, entre autres, une mesure différentielle précise des courants de bras. Ensuite, une méthode de génération modulaire de porteuses triangulaires auto-alignées est proposée et validée grâce à la réalisation d'une maquette de test. L'association de ces deux techniques nous permet de proposer une architecture entièrement modulaire ne nécessitant plus de circuit de commande superviseur
Development of interleaved power converters with coupled inductors has enhanced converters performances (better power density, eciency, transient response. . .). Such improvements lead to the necessity of a precise current-sharing in the converter legs, and consequently to much more complex control strategy for those converters. First step is to determine current sharing loop transfer function in order to choose the kind of sharing corrector and calculate its parameters. State-space representation is used to consider any coupling topology. Because ux induced in coupled inductors must be controlled with accuracy, a bibliography study emphasizes the lack of precision in present current-sensing techniques. Then, a precise analogical emulation of currents in every leg, based on only one current sensor, is proposed. Two prototypes have been developed and validate this approach. Finally, because of growing interest of industrial in modular architectures, two innovations which avoid the use of central specic circuit are presented. First, a masterless and modular current sharing technique is proposed and tested : it allows a very precise dierential current measurement and regulation. Then a modular generation of self-aligned triangular carrier for interleaved converters is proposed and conrmed by test. The association of both techniques leads to a full masterless and modular approach for the control circuit of parallel converter with coupled inductors

Abstract:
Boost dc-to-dc converters have very good source interface properties. The input inductor makes the source current smooth and hence these converters provide very good EMI performance. On account of this good property, the boost converter is also the preferred converter for off-line UPF rectifiers. One of the issues of concern in these converters is the large size of the storage capacitor on the dc link. The boost converter suffers from the disadvantage of discontinuous current injected to the load. The size of the capacitor is therefore large. Further, the ripple current in the capacitor is as much as the load current; hence the ESR specification of the tank capacitor is quite demanding. This is specially so in the emerging application areas of automotive power conversion, where the input voltage is low (typically 12V) and large voltage boost (4 to 5) are desired. The first part of this thesis suggests multi-phase boost converter to overcome the disadvantages of large size storage capacitor in boost converter. Comparison between the specification of single stage and multi-stages is thoroughly examined. Besides the average small signal analysis of N converters in parallel and obtaining an equivalent second order system are discussed. By paralleling the converters the design of closed loop control is a demanding task. To achieve proper current sharing among the stages using current control method is inevitable. Design and implementation of closed loop control of multi-phase boost converter both in analog and digital is the topic of next part of the thesis. Comparison between these two approaches is presented in this part and it will be shown that digital control is more convenient for such a topology on account of the requirement of synchronization, phase shifted operation, current balancing and other desired functions, which will be discussed later in detail. A new direct digital control method, which is simple and fast, is developed. Two different realizations with DSP controller and FPGA controller are considered. In the last part of the thesis a novel soft switching circuit for boost converter is presented. It provides Zero Voltage Switching (ZVS) for the main switch and Zero Current Switching (ZCS) for the auxiliary switch. The paper presents the idealized analysis giving all the circuit intervals and the equations necessary for the design of such a circuit. The proposed soft switching circuit is particularly suited for the tapped-inductor boost circuit with a minimum number of extra components. Extension of the method to tapped inductor boost converter addresses the application of Zero Voltage Transition (ZVT) to high conversion ratio converters. Extension of the method to multiphase boost converter shows that with less number of auxiliary switches soft switching operation can be achieved for all interleaved switching devices. Several laboratory prototype boost converters have been built to confirm the theoretical results and design methods are matching with both simulation and experimental results.
