摘要：

To improve the conversion efficiency of the three-phase inverter, a novel topology of three-phase resonant pole soft-switching inverter is proposed. By adding a simple auxiliary circuit on each phase of the bridge arm, the main switches realize zero-voltage turn-on and zero-current turn-off. Metal Oxide Semiconductor Field Effect Transistor (MOSFET) or Insulated Gate Bipolar Transistor (IGBT) which is used as the main switch of the inverter could realize the lossless switching, so as to solve the problem of capacitive turn-on loss caused by the MOSFET internal junction capacitance and the turn-off loss caused by the IGBT trailing current. This paper analyzes the working process of the circuit. The experimental results show that the switching devices achieve soft-switching. Therefore, the topology is of great importance to improve the performance of the inverter. © 2019, Chinese Institute of Electronics. All right reserved.
