Abstract：Using an asynchronous motor as controlled object,the new ADRPI soft-switch three-phase invert-er 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 in-verter 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 im-proved.
