Abstract

The disclosed self tuning electrical system includes a transformer having a primary and a secondary. The transformer primary is coupled to receive an electrical drive signal and the transformer primary presents an electrical input impedance to the drive signal. The transformer secondary is electrically connected to a load circuit. The system includes tuning components for tuning the system by adjusting a relationship between the inductance provided by the transformer and the capacitance of the load circuit according to a function of the input impedance. The tuning components may tune the system by adjusting the inductance provided by the transformer, and the tuning components may tune the system by adjusting the capacitance provided by the load circuit.
