摘要：

In order to realize efficient work of the inverter, a parallel resonant dc link inverter with low-loss auxiliary circuit is proposed. The resonance of the auxiliary circuit on the dc link is triggered only in the rising process of the voltage across the dc link. In the descending process of the voltage across the dc link, or when the instantaneous value of load current is low, the auxiliary circuit does not resonate, which is beneficial to realizing the low-loss of the auxiliary circuit. The working process of the circuit is illustrated. The experimental results show that the switching device has achieved soft switching. Therefore, this topology structure is instrumental in optimizing the efficiency of the inverter. © 2022 Chinese Institute of Electronics. All rights reserved.
