摘　　要：互补ＳＰＷＭ 波信号源是逆变器主电路的控制信号，为保证逆变桥不发生同臂直通现象，设定可调的死区时间是十分必要的。文中介绍了采用普通元器件，为互补ＳＰＷＭ 信号设定可调的死区时间，确保逆变器安全工作。The complement SPWM signal source is the control signal of the inverter circuit. To avoid conduction through occurred in the inverter, it is necessary to design an adujstable dead time. This paper introduces an approach of designing the adjustable dead time of the complement SPWM signal source using general devices to assure the safe operation of the inverter.
