The modulated pulse train is then applied to more » each of the motor phase inputs with respective phase shifts of 120.degree. The carrier waveform frequency is a multiple of the motor stator frequency. is the angular displacement of the pulse center at the motor stator frequency from a fixed reference point on the carrier waveform. In the disclosed method of pulse width modulation, both edges of each pulse of a carrier pulse train are equally modulated by a time proportional to sin. Y10 - technical subjects covered by former uspcĪn inverter is connected between a source of DC power and a three-phase AC induction motor, and a micro-processor-based circuit controls the inverter using pulse width modulation techniques.Y04 - information or communication technologies having an impact on other technology areas.Y02 - technologies or applications for mitigation or adaptation against climate change.
