A transformer based inverter system comprises a transformer core, a secondary winding wound around the transformer core, a plurality of primary winding circuits each comprising a clockwise or counterclockwise winding wound around the transformer core and a switch operative to selectively open and close to allow current to flow through the winding. Each primary winding circuit is connected to terminals of a DC generator to drive current around the transformer core in a clockwise or counterclockwise direction. A control system is operative to open and close the switches such that an input DC voltage from a generator is transformed and inverted into an AC voltage that has a frequency and voltage equal to a desired frequency and voltage, and such that as the input DC voltage varies within a range, the AC voltage at the terminal ends of the secondary winding remains substantially constant.
