Abstract :
A three-phase, single-stage, isolated PWM rectifier capable of power factor correction and low harmonic current distortion and at the same time realizing zero voltage switching for all power semiconductor devices is proposed. The circuit is thoroughly analyzed. Design equations and tradeoffs are provided. The performance of the circuit is demonstrated through the implementation of a 2 kW, 91 kHz, digital signal processor controlled prototype. The isolated DC output voltage is regulated at 50 V. The conversion efficiency is around 93%
