| Abstract: | A bidirectional ZVT PWM soft switched three phase inverter is presented in this paper,which can simplify the control circuit greatly by naturally occured resonance.The modified space vector modulation makes true PWM operation possible.The operation principle and control strategy are analyzed in detail,and an optimizing program of designing resonant parameters is provided.On account of simulating the performance on a 7.5kW induction motor,with a switching frequency of 20kHz,it is proved that the proposed solution is correct and feasible. |
