A New Frequency Modulation Technique for Audible Noise Reduction in PWM Inverter-Fed Induction Motors (original) (raw)

1992

Abstract

The development of pover electronic devices and various microprocessor control techniques have been surmounting the critical point of the nonlinear characteristics in electric machine drives, and the results made more use of the AC motor system. But, veil known technique to drive AC machine in recent days, SPWM inverter-fed induction machine produces mechanically and electrically generated unpleasant audible noise.
