摘要

The power conversion circuit of a three phase Vienna or Modular-Boost switching power factor corrected (PFC) rectifier uses three controlled switches, eighteen diodes and two output split capacitors. Three PFC controller circuits are necessary for conversion circuit's voltage regulation, power factor control and input current waveform improvement. The circuit has been modified to have fewer active and passive components in the power circuit. The input voltages and currents are sensed and conditioned to one voltage and one current signal for the feedback controller circuit. Reduction of controlled switches, diodes of the power circuit, sensors, isolation, base drive supply circuits makes overall operation of the circuit reliable. The proposed three phase boost PFC rectifier circuit is easy to design, fabricate, operate and maintain. It occupies less space and is lighter in weight. Disadvantages of unidirectional power flow and only step-up voltage gain characteristics of conventional three phase Vienna/Modular-Boost rectifiers remain in the proposed modified circuits.
