ABSTRACT:
An AC motor drive includes a PWM voltage inverter which is responsive to voltage commands from a synchronous current regulator to control motor armature current and rotor speed. A feedforward voltage is also applied as input to the PWM voltage inverter and it is compensated to boost the effective gain of the inverter when it is operated in the pulse dropping region. The compensation values are precalculated and stored in a table from which they are read during drive operation.
