Study on Electrical Automation with Design of the PWM Signal Generator Based on MSP430

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. The PWM signal generator can be applied in the field of converting technology in power electronics and electrical automation.
