摘　　要：提出了一种基于STC12C5A60S2单片机系统产生两路PwM移相180°方波的控制方案，即每个桥臂两个开关管互补导通，其特点是频率、占空比、死区实时可调，成本低、可靠性高，并给出了实现方法、软件流程图及部分实验波形。Put forward a control strategy based on STC12C5A60S2 single-chip microcomputer system which generates two-way PWM phase shift 180° square wave, i.e. two switch tubes on each bridge arm are in alternate switch mode. It has the characteristics of real-time adjustable frequency, duty cycle and dead zone, and low cost, high reliability. And also provide the realizable method, software flow diagram and some experiment waveforms.
