Abstract
An induction heating device includes a first resonance circuit comprising a first working coil and a first resonance capacitor, a first inverter electrically connected to the first resonance circuit and configured to perform a first switching operation to thereby apply a first resonance current to the first working coil, a first group of snubber capacitors that are configured to be electrically connected to the first inverter, the first group of snubber capacitors comprising a first snubber capacitor and a second snubber capacitor, and a first relay configured to selectively connect the first group of snubber capacitors to the first inverter.
