Patent ID: 7339809

Claim:
A distribution system for controlling an unregulated output waveform from a power source, comprising: a modulator coupled to the power source that receives the unregulated output waveform and is operable to produce a first composite waveform; a mixing unit coupled to the modulator that is operable to generate a second composite waveform by introducing a frequency modulated component into the first composite waveform; a demodulator coupled to the mixing unit that demodulates the second composite waveform and generates a third composite waveform, wherein the demodulator includes: an error determination component configured to output an error signal based on a difference between the second composite waveform and a periodic waveform; and a switch configured to receive the error signal and to control output of the third composite waveform based on the error signal; a transformer interposed between the demodulator and the mixing unit that includes a plurality of taps that are individually selectable to provide a desired transformation of the second composite waveform; and a filter network coupled to the demodulator that receives the third composite waveform and configured to select a desired spectral portion of the third composite waveform, the third composite waveform being coupled to a load.
