An electronic high frequency induction heater driver, for a variable spray fuel injection system, uses a scalable array of zero-voltage switching oscillators that utilize full and half-bridge topology wherein the semiconductor switches are synchronous within each bridge for function, and each bridge is synchronized for function along the entire array. 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 each 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.
