Abstract
Provided is an induction heat cooking apparatus. The induction heat cooking apparatus includes a rectifying part rectifying an input voltage to output a DC voltage; an inverter switching the DC voltage outputted through the rectifying part to generate an AC voltage; a first heating part operated by the AC voltage applied from the inverter; a second heating part connected to the first heating part in parallel, the second heating part being operated by the AC voltage applied from the inverter; and a switching signal generation part controlling an operation state of each of the first and second heating parts from the inverter according to an operation mode inputted from the outside. The switching signal generation part includes a pulse transformer.
