| Abstract: | A three-phase soft switching PFC converter employing compound active clamping technique is proposed. A improved SVM is adopted in the CAC three-phase PFC. It can effectively reduce the loss caused by diode reverse recovery of the bridge switch's body diode. Both the main switch and the auxiliary switch can achieve Zero-Voltage-Switching (ZVS). In addition, all the switches have low voltage stress. The switching frequency of the main switch and the auxiliary switch is fixed, thus the input current waveform is good. One DSP controlled 4kW PFC converter prototype with CAC is implemented |
