Abstract

The method to improve the efficiency of a slightly loaded induction motor is suggested. It is based upon the optimal efficiency slip tracking by adjusting the voltage to frequency ratio(V/f). It is adopted the converter-inverter fed induction motor drive system. All the control loops are implemented bh the Z-80 microprocessor. By this method, 10% or more improvement is achieved at a few fraction of the full load.
