Abstract :
Power factor corrected rectifiers are new tendency in the development of power supplies. The present paper proposes a new simplified topology for three-phase applications, with only two active switches, which is able to generate symmetrical currents in the line. The power circuit and DSP control circuit are presented. Complete system modelization and simulation results with closed loop operation are given, as well as the results of an experimental verification
