Stress analysis and dimensioning of three resonant convertortopologies

摘要

This paper presents a comparative study of the stresses applied tothe semiconductors and reactive components making-up resonant convertorsworking above the resonance eigenfrequency of the oscillatory circuit.The convertors studied are the two basic structures (the series- andparallel-resonant convertors) and the series-parallel resonant convertorwith capacitive filter. For each structure the stresses are analysed andthe results tabulated. An example of dimensioning of a 1 kW module foreach of the structures is given
