Abstract
A system for regulating an alternating current voltage source has a pair of P-channel MOSFETs and a pair of N-channel MOSFETs in a bridge configuration with an inductor-capacitor tank there between. A processor in conjunction with a feedback circuit regulates the energy transferred to the tank by modulating the pulse width of signals that are output from the processor and which are used as inputs to the gates of the MOSFETs. By increasing or decreasing the pulse widths transmitted to the various gates of the MOSFETs, the processor increases or decreases the energy transferred to the tank. The feedback circuit is connected between the tank and the processor so that the processor can compare the feedback voltage from the tank to a threshold level in the processor and modify the pulse widths at the output of the processor accordingly.
