Diode rectifiers with large dc-bus capacitors, used in the front ends of variable-frequency drives (VFDs) and other ac-to-dc converters, draw discontinuous current from the power system, resulting in current distortion and, hence, voltage distortion.

Variable-frequency drives (VFDs) with diode front-end rectifiers are typically equipped with a resistor-contactor arrangement to limit the inrush current into the dc-bus capacitors, thereby providing a means for soft charging the dc-bus capacitors. B

In many applications, it is often needed to extend the speed range of an electric motor. In permanent magnet AC motors (PMAC), the maximum speed is limited by the available voltage for a given counter EMF value. Extension of the speed range can be ac
