ABSTRACT:
A computer controlled solid-state switching power factor corrector, which senses the phase angle of each phase of the current as well as the voltage and automatically aligns the current phase angle to the voltage phase angle. This power factor correction is designed to update at the frequency of the power line and to provide a large number of discrete steps of correction.
