A new PWM technique frequency regulated carrier for induction motors supply

A new generated pulsewidth modulation (PWM) technique is presented herein, making it possible to significantly reduce harmonics in comparison to other common real-time PWMs. This reduction means that a motor connected to an inverter driven by this technique will undergo less overheating and vibrations, thereby improving its performance. Index Terms--Frequency modulation, harmonic distortion, pulsewidth modulation (PWM).
