A DC bus filter capacitor of any value further reduces the power factor and increases ... to a THD in all three phase bridge rectifiers. A high frequency ripple voltage, induced by inverter ...

The need for the current waveform to track the voltage on a three-phase power system leads to a second set of requirements, in addition to those for a single-phase power factor correction ... assume ...
