More Information
Summary:An induction heating system with a plurality of resonant inverter tanks can be provided. The induction heating system can include a power source configured to supply power to the heating system and a plurality of parallel resonant inverter tanks in electrical connection with the power source. Each of the parallel resonant inverter tanks can include one or more parallel resonant capacitors, one or more parallel induction coils and one or more switches configured to disconnect each of the parallel resonant inverter tanks from the power source. The induction heating system can include a controller configured to perform operations, wherein the operations include determining when a cooking vessel is present at each induction coil and in response to determining that a cooking vessel is not present at a resonant inverter tank, operating the one or more switches such that the parallel resonant inverter tank is disconnected from the power source.
