Co-axial multi-zone induction cooking apparatus

An induction heating system, the induction heating system comprising:

• a power source configured to supply power to the induction heating system;
• a plurality of parallel resonant inverter tanks configured to be in electrical communication with the power source, wherein each of the parallel resonant inverter tanks include one or more resonant capacitors, one or more induction coils and one or more switches configured to disconnect each of the parallel resonant inverter tanks from the power source, wherein the one or more induction coils comprise one or more outer coils and one or more inner coils respectively;
• a controller configured to perform operations, wherein the operations include determining whether a cooking vessel with a diameter more than 10% greater than an outer diameter of the one or more inner coils is present at one of the one or more induction coils, and in response to determining that a cooking vessel is present at a resonant inverter tank, operating the one or more switches such that the parallel resonant inverter tank is connected to the power source.
