Full textImprovement of power density is a bigchallenge for embedded electric vehicle chargers.Goal of the study is to reduce the volume of the DCDCcharger which contains a bulky transformer. Thekey point is to use wide band gap transistors (GaN) toincrease the charger switching frequency. High switchingfrequency can improve power density but theinconvenient is the increase of switching and transformerlosses. The PhD dissertation is organized inthree steps. First step is the definition of a charger topology.This topology is optimized to reduce transformerlosses. Second part of the study is the theoreticaldesign of a high power density transformer. A completetransformer parametric model is presented withFinite Element Analysis. Third part present the prototypeand test results of the charger DC-DC. Electricalbehavior, volume and efficiency results are discussedin this part.Universit ´

Full textThe aim of this thesis is the study and design of a soft switching high power converter for transport applications and especially heavy vehicles. First part is dedicated to the choice of the converter structure and a detailed behavioural study. Parameters of this converter has been identified and quantified such as 18 kW as nominal power, 400 V as output voltage and 67 V as input voltage from a DC fixed source. Switching output frequency has been fixed to 40 kHz. Second chapter will present the study of a high frequency transformer integrated into the this converter. A behavioural model of the transformer has been defined in order to perform simulations by means of SABER software. Two technologies of transformers are used for this case : as a first classical one, a wounded transformer is used and for the second one planar technology is tested. The author validates these models by simulation and experimental results. In the third chapter, the command strategy of this converter is detailed with the driving of the 16 electronic switches and also constraints on the signals in order to perform a good behaviour in soft switching techniques. The fourth part presents various models developed in order to simulate this converter by SABER software. Linear switching semiconductor MOSFET and IGBT models have been defined. A study and a proposal of a brushless DC motor model with trapezoidal back emf are detailed. The model is then written using MAST programming language. Finally various command blocks have been described. In the fifth chapter, the author presents experimental test results which has been performed on an test bench but for electrical powers up to9 kW with passive loads (RL) and active load (brushless DC motor). Various tests have been proposed to validate this structure with special attention to efficiency and losses under different load conditions. As a conclusion the author shows the interesting case when more than one motor is used and the electrical energy will be fed to the motors by means of AC high frequency energy distribution

Full textChapter 1 introduces the topic and its associated context. Locks are identified.Chapter 2 is reviewing state of the art of winding topologies. Their strengths and weaknesses are discussed. Then, materials required for transformers microfabrication (conductors, magnetic material and insulation material) satisfying both high temperature and high frequency criteria are identified. Finally, LTCC fabrication process, an alternative to process used here, is presented.Chapter 3 discuss modelisation and design of transformers by defining the structures and its degrees of freedom. Analytical expressions and finite element analysis allows evaluation of interleaved transformer and tapped transformer within a good accuracy.Chapter 4 present technological process involved in batch-processed fabrication of transformers onto magnetic substrate. Processes are substrate insulation, conductors electrolytic growth of windings and final assembly of transformers.Chapter 5 present characterization methods of several properties of the transformers such as DC winding resistance, self-inductances of windings and isolation capacitance between primary and secondary winding. These characterizations confirm analytical expressions and their underlying hypothesis as well as magnetostatic and electrostatic finite element analysis.Chapter 6 concludes on work achieved during this PhD thesis and opens to further perspectives

Full textDuring the re-energization of the auxiliaries of a nuclear or hydraulic power plant, the most dangerous step is the re-energization of the power transformer, because of the temporary overvoltage and inrush currents. These transients phenomenon causes undesirable effects for both network and for the power transformer (electrodynamic forces over the windings, the magnetic circuit’s vibration, noise and the premature aging of the transformer). The goal of these thesis is to suggest new methodologies allowing us to evaluate unknown parameters (the residual flux’s values in the magnetic circuit before transformer’s energization). According to the latest problems in order to evaluate it (no direct method, derivation, voltage measurement error, etc) two new methods based on the previous magnetization of the magnetic circuit (prefluxing method) and on the leakage flux measurement of the magnetic circuit (direct measurement of the flux by measuring the magnetic induction method) are proposed

Full textThis thesis concerns the study and the rating of a high voltage multicellular converter with an intermediate medium frequency stage dedicated to railway traction. The objective is to reduce the weight and the volume of the AC-DC conversion stage which is implemented in railway engines running on 25kV-50Hz or 15kV-16Hz2/3 railways. Reduction on weight and size of the AC-DC converter may be applied on multiple unit trains where the transformer causes room loss for passengers and on locomotives and high speed trains where the axle load is limited. On one hand high voltage switches are required in order to minimize the number of cells used to build the converter. On the other hand, reducing the size and the weight of the transformer requires a high switching frequency, causing high commutation losses. To achieve soft switching conditions with high voltage semiconductors, the proposed topology is based on an association of dual structures. Each elementary converter combines a controlled turn-off voltage source inverter and a controlled turn-on current source inverter. In order to estimate the efficiency of the new topology, a prototype of one elementary cell working at 280 kVA, was built at the Power Electronics Associated Research Laboratory (PEARL). The switches are standard 6.5 kV/200A IGBTs modules. Soft-switching tests, in real operating conditions, allow evaluating IGBTs and diodes switching losses. Thanks to these results, it is possible to find the structure operating limits and to size the transformer considering the trade-off between the system efficiency and the transformer weight
