A DSP based Control for a Symmetrical Three-Phase Two-Switch PFC-Power Supply for Variable Output Voltage
Power Factor Corrected rectifiers are new tendency in development of power supplies. The present paper proposes a new simplified topology for three-phase applications, with only two active switches and able to generate symetrical currents in the line. Power ciruit and DSP control circuit are presented. Complete system modelization and simulation result with closed loop operation are given, as well as results of an experimental verification.
