ABSTRACT:
A high efficiency, regulated DC supply combines the rectifying and a series regulating elements into one device such as a MOS FET which is gated "on" or "off" by the polarity of an AC voltage from a transformer winding. During the "on" state of the MOS FET a feedback network varies the MOS FET gate voltage as necessary to provide regulation of the DC output voltage during the "on" period.
