摘　　要：以异步电机为被控对象,设计了一种基于辅助二极管谐振极逆变器(ADRPI)的新型软开关三相逆变器及其驱动控制电路,并在实验基础上对设计的逆变电路及驱动控制电路提出了改进措施,即采用新型的软开关逆变电路及对驱动控制电路中元器件参数进行选优.实验结果证明,ADRPI软开关逆变电路输出波形中的尖峰脉冲得到了有效抑制,改善了逆变电路的输出特性,提高了输出电流的质量.Using an asynchronous motor as controlled object,the new ADRPI soft-switch three-phase inverter circuit and the actuation control circuit diagram of inverter electric circuit were designed,and based on many experiments for inverter circuit design and driving control circuit the concrete improvement measures were proposed,using the new type of soft switch inverter circuit and the selection and design of the drive control circuit component parameters. The experimental results showed that pinnacle impulse from the inverter circuit output signals of ADRPI soft-switch invertor circuit was restrained and the inverter circuits output characteristic was improved,so the quality of output current of inverter has been obviously improved.
