ABSTRACT:
A low power high efficiency power supply provides a high voltage level output, which can be used to drive a variety of devices. The power supply uses controlled feedback to a comparator, which in turn drives an AND gate logic device. The comparator drives the AND gate logic device to gate an input clock signal the output of the AND gate logic being supplied to a resonant circuit that is at or near the resonant frequency of the input clock signal. The output of the resonant circuit is rectified to provide the final voltage output. The final voltage output is attenuated and supplied as feedback to the comparator.
