AbstractAn AC-DC converter that includes a plurality of power conversion units that overlay their signals to generate a DC signal with low voltage level, small voltage and current ripples, but high DC current. The DC signal is further filtered by a LC low pass filter to further minimize the ripples before output to the load. In one embodiment, the plurality of power conversion units is preferably powered by a plurality of input pulse generators. In an alternative embodiment, the power conversion units is powered by a input pulse generator circuit that includes a plurality of n-channel MOSFETs arranged in a full bridge configuration whose gate voltages are controlled by a plurality of pulse generators.
