    • PURPOSE: A protection circuit for an induction heating cooker and an induction heating cooker with the same is provided to perform the operation of an induction heating cooker by blocking the operation of an inverter circuit in the eccentric state of a container and the no load state. CONSTITUTION: A protection circuit for an induction heating cooker and an induction heating cooker with the same comprises a power supply unit(9), an inverter unit(5), an inverter unit driver circuit(6), a protection circuit(30), a resonance potential sensor(7), a working coil(20) and a MICOM(8). The power supply unit converts AC power supply into DC power supply supplies the AC power supply to the inverter. The inverter includes an isolated gate bipolar transistor. The inverter unit driver circuit operates the inverter unit. The inverter unit driver circuit functions as maintaining the constant output of the inverter unit. The inverter unit driver circuit is linked with the MICOM. The resonance potential sensor measures the voltage value of the resonance current applied in the working coil.

    • PURPOSE: An electric hob and a control method thereof are provided to prevent the temperature of a casing space with a heating source from excessively rising by controlling a drive level of a heating source based on the temperature of a heating source drive part. CONSTITUTION: An electric hob comprises a casing, a heating source(300), a heating source drive part(200), a sensor(400), and a controller(500). The casing forms outer appearance. The heating source is formed in the internal space of the casing. The heating source drive part drives the heating source at a fixed drive temperature. The sensor monitors the temperature of the heating source drive part. The controller sets up the maximum drive temperature of the heating source according to the temperature of the heating source drive part.
