摘　　要：给出了一种新的SPWM控制算法。采用该方法可以很方便的实现SPWM变频逆变的控制,并以增强型高速51单片机W77E58为主处理器构成系统,实现了三相变频逆变电源。该电源具有频率、电压的调节、指示及过流保护等功能。With the new SPWM controlling computation worked out in the essay, SPWM frequency conversion contravariance could be conveniently realized to establish system based on intensive high- speed SCM W77E58 to realize triphase frequency conversion contravariance power. The power proved functions with adjusting frequency and voltage, signaling and current prevention.
