An electronic high frequency induction heater driver, for a variable spray fuel injection system, uses a zero-voltage switching oscillator that utilizes a full H-bridge topology with inductors between semiconductor switches wherein the semiconductor switches are synchronized within the bridge for function. The induction heater driver, upon receipt of a turn-on signal, multiplies a supply voltage through a self-oscillating series resonance, wherein one component of the tank resonator circuit comprises an induction heater coil magnetically coupled to an appropriate loss component so that fuel inside a fuel component is heated to a desired temperature.
