摘要
When a single-phase full-bridge inverter works in the hard-switching state, the switching loss will increase significantly with the increasing of switching frequency, so that it will affect the efficiency of the inverter. In order to solve this problem, an energy-saving single-phase full-bridge resonant pole inverter is proposed. When the inverter is in the dead state, the voltage across the resonant capacitor in parallel with the main switch can decrease to zero via the resonance of the auxiliary circuit. The main switch can achieve zero-voltage switching, and the bidirectional auxiliary switch can realize zero-current switching. The operation process of the circuit in a switching cycle is analyzed. The experimental results show that the main switch and auxiliary switch can realize soft-switching. Therefore, the single-phase full-bridge soft-switching inverter can be applied at high switching frequency. © 2019, Chinese Institute of Electronics. All right reserved.
