摘要：
To realize high-efficiency operation, a novel three-phase resonant pole inverter with soft-switching function is proposed. When the inverter is in dead-zone state, the auxiliary circuit will start to resonate. The voltage across the main switch on the bridge arm which will be turned on can become zero in advance, so it can obtain zero-voltage soft switching, and the auxiliary switch can also obtain zero-current soft switching. In addition, the auxiliary switch is connected with the transient voltage suppression diode, which can not make the auxiliary switch bear excessive high frequency transient voltage when the circuit is in resonant state. The working process is illustrated. The experimental results show that switching devices is in the state of soft switching. The circuit structure can optimize the performance of the inverter. © 2022 Chinese Institute of Electronics. All rights reserved.
