Abstract :
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. The relationship between the efficiency of the converter and the circuit resonant parameters is studied. The EMI noise of the proposed converter in hard switching and soft switching conditions is also investigated. The analysis results are verified by a 10kW prototype.
