PURPOSE: To provide an inverter control method by which a switching element can be reliably turned off before an electric current reaches zerocross time in translocation control in an inverter. CONSTITUTION: An inverter control method is provided with transistors 13 and 14 to reverse the direction of an electric current flowing to an induction heating coil 19, a current transformer 20 to detect the electric current of the induction heating coil 19 and a coil current phase discriminating circuit 21 to discriminate a phase of the electric current flowing to the induction heating coil 19 by output electric current of the current transformer 20. The transistors 13 and 14 are constituted so as to be turned off by a discriminating result of the coil current phase discriminating circuit 21. |
