ABSTRACT:
An inverter is operated to eliminate hiss in the control of the speed of an induction motor using an inverter of variable frequency. The voltage is matched to the selected frequency to avoid such hiss and control of the voltage is effected by regulating spacing between the pulses outputted by the pilot unit to the gates of the MOSFETs or IGBTs forming the arms of the inverter.
