摘　　要：为改善单相全桥逆变器的性能,提出了一种新型单相全桥谐振直流环节逆变器.位于直流环节的辅助电路能提升直流母线电压稳态值,减少直流母线电压的零状态对直流电压利用率的负面影响.文中分析了逆变器的换流过程.实验结果表明开关器件完成了软切换,逆变器性能得到了改善.In order to improve the performance of single-phase full-bridge inverter,a novel single-phase full-bridge inverter with a resonant DC link is proposed.The auxiliary circuit in the DC link can improve the steady state value of the DC bus voltage,and reduce the negative effect of DC bus zero-voltage state on DC voltage utilization.In this paper,the commutation process of the inverter is analyzed.The experimental results show that the switching devices achieve soft switching,and the performance of the inverter is improved.
