A symmetrical 3 phase - 2 switch PFC-power supply for variable output voltage

Power Factor Corrected rectifiers are a new tendency in development of power supplies. In the last few years, a lot of R&D activities have led to a new category of products for one phase applications. In this comtribuction, a new simplified topology is proposed for three-phase applications, using only two active switches, and able to generate symmetrical currents in the line. Power circuits are presented. Complete simulator results with closed loop operation are given, results of an experimental verification
