An amplifier circuit for efficiently driving a tuned resonant load where the amplifier circuit controls the continuously variable resonant frequency of the tuned resonant load so as to match step changes or slower changes in the frequency of the signal with which it is being driven. The circuit includes a tuned resonant load, a driver, a controller and a feedback loop. The driver is coupled to the load and drives it with a driving signal at a frequency under the control of the controller. The controller dynamically controls the resonant frequency of the tuned resonant load in response to an error signal received through the feedback loop. The error signal represents the mismatch in phase between the resonant phase of the load current and the phase of the driving signal, or between the resonant phase of the tuning capacitor voltage offset by 90 degrees and the phase of the driving signal. The controller also controls the pulse width of the driving signal, which controls the energy transferred to the load, and ensures the pulses are centered within the half cycle of the load current to avoid advancing or retarding the phase of the load current in each half cycle.
