摘要：

In order to optimize the performance of three-phase inverter, a high efficiency three-phase resonant inverter is proposed.When the auxiliary resonant circuit on each phase leg works in the commutation process of the inverter, the voltage across the capacitor parallel with the main switch can periodically change to zero, so that the main switch device can achieve zero-voltage soft switching, and the switching devices in the auxiliary resonant circuit can achieve zero-voltage turn-on and zero-current turn-off.Soft switching can reduce switching loss and improve the efficiency of the inverter.In this paper, the working flow of the circuit is analyzed.The experimental results on the 3kW prototype show that both the main switch and the auxiliary switch achieve soft switching.Therefore, this topology structure has reference for the research and development of high performance three-phase inverter. © 2021, Chinese Institute of Electronics.
