Abstract:
An induction heating device includes a working coil group including a first working coil and a second working coil that are electrically connected in parallel to each other, an inverter configured to perform a switching operation to supply resonance current to at least one of the first or second working coil; a first semiconductor switch electrically connected to the first working coil to turn on and turn off the first working coil; a second semiconductor switch electrically connected to the second working coil to turn on and turn off the second working coil; and a controller configured to control operation of the inverter and the first and second semiconductor switches, respectively. The controller turns off the inverter before turning off at least one of the first semiconductor switch or the second semiconductor switch.
