A resonant DC link current-source zero-voltage switching PWM rectifier is put forward to solve the switching loss problem under high switching frequency.The auxiliary circuit is in parallel with the DC bus and is added in the DC link.Only one auxiliary switch set in its auxiliary circuit.In the process of commutation

zero-voltage switching can be achieved in the main switch and zero-current switching can be achieved in the auxiliary switch.Furthermore

when multilevel PWM control strategy is adopted by the rectifier

the auxiliary circuit only needs to work for one time in each switching period.This paper analyzed the resonant commutation process.The simulation results show that the characteristics of the simulation waveforms are consistent with the theoretical analysis

the switches can realize soft-switching and the rectifier can run stably.The current-source energy-saving rectifier with zero-voltage switching can be operated under high switching frequency and high power applications.
