ZCS-PWM full-wave boost rectifier with unity power factor and low conduction losses

A full-wave boost rectifier (FWBR) realized by zero-current-switching pulsewidth-modulation (ZCS-PWM) control to achieve unity power factor is presented. Two resonant cells are configured in the presented FWBR to perform ZCS in the power switches and to preregulate the input current to follow up the input voltage. Only one diode and one power switch loss are included in the proposed FWBR during the rectification. Four transition states for describing the behavior of the ZCS-PWM FWBR in one switching period are described. A small-signal model is built for the system analysis, and an average-current-mode control is employed to formulate the input current waveform with low harmonics. The control strategy and design consideration are programmed to realize a 600-W ZCS-PWM FWBR, which provides high power efficiency of 95% and high power factor over 0.99.
