摘要
介绍一种高精度、高性价比的PWM信号发生器的设计。该信号发生器以STM32单片机为核心控制单元,通过对单片机定时器的控制来实现对输出波形的频率、电压幅值、占空比的连续调节,并能对输出信号参数进行实时显示。经实验验证,该信号发生器便于观察和调节,完全满教学和生产中对PWM信号发生器高精度和经济性的要求。
A pulse-width modulation(PWM)signal generator is introduced,which has high-accuracy and high performance-price ratio.Due to the requirements of the output waveform,STM32 chip microcomputer is served as its control unit,so the output waveform parameters of frequency,amplitude and duty ratio can be regulated continuously,and displayed real time.As experiment results shown,the system is convenient to adjust and observe,and meets the needs of the high-accuracy and economy of education and produce.
