INDUCTION HEATING APPARATUS AND METHOD FOR CONTROLLING THE SAME

A controller of the induction heating apparatus in one embodiment may determine an overlapped period of a resonance current value of a working coil and a driving voltage value of a switching element included in an inverter circuit. The overlapped period may denote a period for which the resonance cu...

Beschreibung
Zusammenfassung:	A controller of the induction heating apparatus in one embodiment may determine an overlapped period of a resonance current value of a working coil and a driving voltage value of a switching element included in an inverter circuit. The overlapped period may denote a period for which the resonance current value and the driving voltage value are all positive numbers. The controller may determine whether a driving state of the induction heating apparatus is normal or abnormal based on a time point at which the overlapped period appears. When determining that the driving state of the induction heating apparatus is abnormal, the controller may stop driving of the working coil.
