| Abstract: | This paper proposes a novel circuit of DC Rail Paralle Resonant Zero Voltage Transition Voltage Source Inverter(DC Rail PR ZVT VSI')for three phase motor drive.In this circuit,all switches are turned on or turned off under the Zero Voltage Switching(ZVS) or Zero Current Switching(ZCS).Power ratings of the resonant components and auxiliary switches the proposed circuit required are small.The control is simple and less dependant on load current,and the time of transition is freely selected.This paper gives details of the theoretical analysis and calculation.And lastly,the validity and the efficiency of the circuit are tested and verified by experiment results. |
