Abstract :
This paper presents the analysis of an isolated three-phase converter operating in soft commutation as a battery charger. The structure works with a high power factor without intermediate circuits. Its main features are: simplicity of control, driver circuit, and robustness of power circuits, Principles of operation, design procedure, simulation and experimental results obtained from a laboratory prototype (55 A/48 V) are presented
