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