摘要

单相全桥逆变器处于硬开关状态时，随着开关频率的增大，开关损耗明显增大，影响逆变器效率的提高.为解决这一问题，提出了一种节能型单相全桥谐振极逆变器，在逆变器处于死区状态时，将要开通的主开关并联的谐振电容的电压能减小至零，主开关动作时能完成零电压软切换，双向辅助开关动作时能完成零电流软切换.讨论了电路的工作流程，实验结果表明主开关和辅助开关完成了软切换动作.该单相全桥软开关逆变器可以向高开关频率的场合推广应用.

Abstract

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.
