Abstract
A controller is connected to at least one transistor of the transistor driving circuit and connected to the at least one current sensing element to detect the current through the induction heating coil and in response to the current through the at least one current sensing coil exceeding a limit level sending a control signal to the at least one transistor of the transistor driving circuit to temporarily turn off the at least one transistor.
