| 摘 要： | 介绍了可由直流电压、正弦交流和任意波形信号作为基波控制占空比的PWM信号发生器的设计.基波信号由MSP430F169单片机系统产生,PWM调制波由压控振荡器产生,两信号经高速比较器调制产生PWM信号.实现了PWM信号频率可调、基波频率和基波波形可程序设置等功能,并可产生三相SPWM信号.

| Abstract: | The PWM signal generator,in which the DC voltage,sine AC or arbitrary waveform signal can be the base wave to control the duty cycle,is designed in this paper.The high-speed comparator modulates the two signals,one is the base wave signal generated by MSP430F169 and the other one is the PWM modulated wave signal generated by the voltage controlled oscillator,and then generates the PWM signal.The frequency of the PWM signal can be regulated,the frequency and waveform of the base wave can be programmed and the three-phase SPWM signal can be generated. |
