Three-phase input line power is converted to a sine-coded, variable frequency output, which provides optimum speed control of any conventional squirrel cage induction motor and permanent magnet motor. The use of IGBTs (Insulated Gate Bipolar Transistors), with a carrier frequency range of 1 kHz to 12.5 kHz, permits quiet motor operation.

A three-phase, 230 V induction motor is operating at no-load condition with rated voltage applied. Equivalent circuit parameters are. It is known that the rated voltage core losses are equal to the rotational losses. Assume that for this no-load condition the coil resistive voltage drops and the leakage reactance voltage drops can be neglected.
