Abstract :
The ZVS-SVM controlled three-phase boost rectifier proposed by the authors 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 switch devices operating at the 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 switches´ voltage stress and circuit parameters is studied. The relationship between the circuit parameters and the soft switching condition is also investigated. The result is verified by a 3kW prototype.
