A study on waveform analysis of PWM Inverter for Trapezoidal modulating signal based on microprocessor

마이크로 프로세서를 이용한 Trapezoidal 변조신호 PWM인버터의 파형해석에 관한 연구

Trapezoidal wave is suitable for the modulating signal of the microcomputer based PWM inverter for the use of motor drives because the switching patterns can be generated by means of on-line computation. In this paper, the output waveform of three-level modulation inverters for the trapezoidal modulating signal is investigated both theoretically and experimentally.
