the current waveform. erefore, current regulation is an issue related only to the low speed mode of
operation. During generation, the mechanical energy supplied by the prime mover will be converted
into an electrical form manifested by the induced EMF. Unlike the motoring mode of operation, this
voltage acts as a voltage source that increases the current in the stator phase, thereby resulting in the
generation of electricity.

e control of electromagnetic torque is the main dierentiating factor between various types of adjust-
able speed motor drives. In switc
