A model and analysis are presented for tuning of a resonant inverter. The model uses linearised phase-frequency characteristic of a tank load near the resonant frequency. To demonstrate the validation of the model, a low-power prototype was implemented using a CD4046 phase-locked loop chip in the tuning circuit.
