Abstract
A tuned power amplifier includes: a tuning capacitor connected in series with a loaded choke that represents an inductance of an oscillator, and a semiconductor power switch connected to the series connection between the tuning capacitor and the loaded choke. The loaded choke may be an induction heating coil of an inductively heated fuel injector. The induction heating coil or the tuning capacitor may be connected to a voltage source. An on state and an off state of the semiconductor power switch may be synchronized with, or at a frequency below, a natural resonant frequency of the tuned power amplifier.
