Abstract
A resonant inverter has a switch network from which a phase signal is provided representing the phase of the switching signal. A resonant tank circuit is coupled to the first switch network output and provides a feedback signal comprising a resonance voltage across a circuit element of the resonant tank circuit. A reference current to be drawn from the input node is set and a reference phase is set based on the reference current. The switching signal for the switch network is controlled based on a phase difference between the resonance voltage and the phase signal, and based on the reference phase. This resonant inverter employs a phase modulation scheme as the control scheme for the switch network of a resonant inverter. This approach is suited for high and very high frequency operation of resonant converters, for example up to tens of MHz.
