ADDITIONAL LOSSES IN PWM INVERTER-FED SQUIRREL CAGE MOTORS

When asynchronous motors are fed from semiconductor inverters, additional losses are generated due to the non-sinusoidal voltage shape. In this paper studies on modulation principles lead to a system which minimizes the additional copper losses. Then these losses are calculated for this modulation system considering the frequency dependent impedances of the motor.
