ABSTRACT:
There is disclosed a circuit for controlling the operation of an electronic cooking system. The circuit comprises a counting inverter for controlling the operation of heating coil, and a pulse generator. The counting inverter comprises a counter for counting the pulses outputted from a microcomputer to deliver a signal for establishing the output of the heating coil and to deliver the output signal of an abnormal state detection circuit to the microcomputer. The pulse generator is disposed between the microcomputer and the counting inverter to synchronize and clear the counter with the output signal of the microcomputer.
