The compound active clamping three-phase boost rectifier proposed by authors has a clamp branch composed of an active switch, a resonant inductor and a clamping capacitor. With a novel zero voltage switching space vector modulation (ZVS-SVM) method, the rectifier can realize ZVS operation for all switching devices and effectively suppress the reverse recovery process of the bridge leg switch anti-parallel...
The ZVS-SVM controlled three-phase boost rectifier can realize ZVS operation for all switching devices. In addition, the anti-parallel diode reverse recovery of all switch devices is well suppressed. Moreover, SVM can be realized with switching devices operating at a fixed switching frequency. In this paper, the soft switching condition of the ZVS-SVM controlled three-phase boost PFC is analyzed....
A zero voltage switching space vector modulation (ZVS-SVM) controlled three-phase boost rectifier is proposed. A branch composed of one active switch, one resonant inductor and one clamping capacitor is added to the six-switch boost rectifier. In addition, a ZVS-SVM for the rectifier is proposed. It can effectively suppress the reverse recovery process of the bridge switch anti-parallel diodes. All...

In three-phase PFC converter, there exist severe switch antiparallel diode reverse recovery problems. The effective measures of compound active-clamping and minimal voltage active-clamping techniques in single phase PFC are extended to three-phase PFC. A family of active-clamping ZVS soft switching PFC converter is derived. They can effectively suppress the diode reverse recovery and realize ZVS for...
