Auxiliary Diode Resonant Pole Inverter （ADRPI） is convenient to control with high reliability and has good prospects for application in AC transmission. This paper presents analysis on the working project of single-leg topology configuration of ADRPI, and brings forward a kind of practical design of circuit detection with zero voltage. Zero Voltage turning on of switch is realized within this circuit with voltage detection, amplifihering, absolute value circuit, comparison, and logic control. Also simulation and experimentation are carried out for further verification, which lays the foundation for practical application of soft switching technology of ADRPI.
