Abstract

See full text

The present disclosure describes devices and methods for improving the power efficiency and control of an induction heating system. In particular, the induction heating system includes a series resonant bridge inverter circuit and a control circuit. The inverter circuit includes one or more induction coils that are structured to inductively couple to the cookware to heat the cookware and a current sensor structured to sense a coil current signal across the one or more inductor coils. In particular, the current sensor is structured to generate a positive sensed voltage signal corresponding to a positive portion of the coil current signal and a negative sensed voltage signal corresponding to a negative portion of the coil current. The control signal is structured to control switching of a first and a second set of switches based on the positive and negative sensed voltage signals.
