ABSTRACT:
A system and method are provided for actively reducing ripple in a supply voltage provided by a switched mode power supply. In general, active ripple reduction circuitry operates to sense the ripple in the supply voltage to provide a signal indicative of the ripple. The signal indicative of the ripple is inverted and provided to the output of the switched mode power supply to substantially reduce or eliminate the ripple in the supply voltage.
