    Patent number: 6304466
    Abstract: An apparatus and method are disclosed for regulating a high voltage DC supply derived from a plurality of unstable high voltage signals. The invention functions to derive a high voltage DC signal from a received unstable high voltage signals. A derived signal is modulated and communicated to a series resonant regulation circuit by varying the operating frequency of the modulation device, while maintaining a fixed pulsed width full duty cycle operation, the output signal is translated in relation to the resonant frequency of the series resonant circuit, causing corresponding variations in the output voltage level.
