Systems and Methods for Distortion Reduction

摘要

Systems and devices for reduction of total harmonic distortion in power supply circuits are presented. Example embodiments of the disclosed systems of total harmonic distortion reduction reduce a low frequency output voltage ripple seen by the voltage control loop by adding a compensating ripple voltage to the output feedback signal. The compensating signal may be scaled by the user to optimize the degree of ripple reduction, and may be automatically adjusted by monitoring circuitry to scale with a power factor control circuit output power level.
