Abstract:
1. A method of converting a duty cycle varied alternating current waveform input into an amplitude varied alternating current waveform output for an electrical load, wherein the average amplitude of said amplitude varied alternating current waveform output is proportional to the duty cycle of said duty cycle varied alternating current waveform input comprising: (a) providing a first energy storage device or plurality of energy storage devices, (b) providing a second energy storage device or plurality of energy storage devices identical to said first energy storage device or plurality of energy storage devices, wherein the two energy storage devices are adapted to function repetitively in two states, A) in the first state, said first energy storage device or plurality of energy storage devices is coupled to said duty cycle varied alternating current waveform input to charge said first energy storage device or plurality of energy storage devices and said second energy storage device or plurality of energy storage devices is coupled to said electrical load, providing previously stored energy to said electrical load, B) in the second state, said second energy storage device or plurality of energy storage devices is coupled to said duty cycle varied alternating current waveform input to charge said second energy storage device or plurality of energy storage devices and said first energy storage device or plurality of energy storage devices is coupled to said electrical load, providing previously stored energy to said electrical load, whereby an oscillation between said two states generates said amplitude varied alternating current waveform output.
