| 摘 要： | 提出了一种控制简单的谐振极型软开关逆变器。用硬开关逆变器的SPWM控制方式实现开关器件的零电流开通和零电压关断，且通过拓扑结构中的储能元件，在死区时间内输出相电流可以续流，减小了输出相电流在低频时的畸变率。最后通过仿真和试验，验证了原理的正确性。

| Abstract: | A new resonant pole inverter with simple control was proposed.There are no auxiliary switching devices in the new topology.Using SPWM of hard switching inverter can realize ZVS and ZCS.In addition, freewheeling of output current can be realized via energy storage components in the dead-time and the effect of dead-time is reduced.The distortion ratio of the output phase current in low frequency is also reduced.The analysis of the circuit was presented.Simulation and experimental results were proposed to verify the theoretical analysis. |

| Keywords: | soft switching inverter dead-time zero current turn on zero voltage turn off |
