noise using pwm to control dc motor
Hi all,
Controlling DC motor with a DC chopper is a well known matter,but,using PWM technique with DC motor seems strange with me!!as we use it in AC systems to improve the harmonic behaviour of the output current"both load and network current waveform".we cost though some switching losses.but,what is the benefit of using PWM on a DC chopper!!??
