Abstract

A system for controlling an induction cooking apparatus includes resonant loads each having an induction coil of said induction cooking apparatus, switching circuitry including a shared half-bridge, and a plurality of secondary half-bridges each cooperating with the shared half-bridge to form a plurality of full-bridge inverters. Control circuitry is configured to determine a plurality of target power levels including a target power level for each one of the plurality of resonant loads, calculate a switching frequency common to the shared half-bridge and the plurality of secondary half-bridges based on the comparison of the target levels, generate a plurality of control signals each for application to a half-bridge of the plurality of secondary half-bridges, calculate a phase displacement for each of the plurality of control signals, and determine a maximum current through the shared half-bridge independent of an orientation of the phase displacement for each of the plurality of control signals.
