摘要: 中小功率单相全桥逆变器常以金属氧化物半导体场效应晶体管(Metal Oxide Semiconductor Field Effect Transistor,MOSFET)作为开关器件,为实现逆变器在高开关频率下的节能运行,本文提出了一种单相全桥节能型谐振极逆变器拓扑结构,其桥臂上分别并联相同的辅助谐振电路.桥臂上的主开关开通前,其并联的谐振电容的电压能周期性变为零,使主开关完成零电压软开通,可消除MOSFET的容性开通损耗,有利于逆变器的节能运行.本文分析了电路的工作模态,实验结果表明主开关器件处于零电压软切换.因此,该拓扑结构对于研发高性能的中小功率单相全桥逆变器具有参考价值.

Abstract: Metal oxide semiconductor field effect transistor (MOSFET) is often used as the switching devices in medium and small power single-phase full-bridge inverters.To realize energy-saving operation of the inverters at high switching frequency,a single-phase full-bridge energy-saving resonant pole inverter topology is proposed.The same auxiliary resonant circuit is connected with parallel on the bridge arm.Before the main switch on the bridge arm is switched on,the voltage across its parallel resonant capacitor becomes zero periodically,which makes the main switch achieve zero-voltage soft-switching and eliminates the capacitive switching loss of MOSFET.It is conducive to the energy-saving operation of the inverter.In this paper,the working mode of the circuit is analyzed.The experimental results show that the main switching devices achieve zero-voltage soft-switching.Therefore,this topology has reference value for the research and development of high-performance medium and small power single-phase full-bridge inverters.

Key words: inverter, bridge arm, auxiliary circuit, parallel, switching loss, zero-voltage turn on, resonance
