Abstract
A power delivery system and method for an induction cooktop are provided herein. A plurality of inverters are each configured to apply an output power to a plurality of induction coils electrically coupled thereto via corresponding relays. A selected inverter is operable to momentarily idle to enable commutation of a relay connected thereto. An active inverter is operable to increase its output power for the duration in which the selected inverter is idled in order to lessen power fluctuations experienced on a mains line.
