Abstract
An induction heating apparatus comprises a heating coil and a transistor which is connected to a direct current power source in series thereto to form an inverter for converting the direct current to an alternating current, and furthermore, a first coupling coil for supplying a forward base current to the transistor is coupled with the heating coil inductively and a second coupling coil for supplying a inverse base current for the transistor is also coupled to the heating coil inductively, and the inverter is controlled by a switching device which is controlled by a control circuit.
