Abstract
An induction heating device includes a first coil that is wound about an axis by a first number of rotations, a second coil that is spaced apart from the first coil in a radial direction and that is disposed radially outward of the first coil, the second coil being wound about the axis by a second number of rotations, and a power supply unit configured to convert alternating current (AC) power and to supply a high-frequency AC to the first coil and to the second coil based on conversion of the AC power. The induction heating device is configured to output a maximum output level in a range from 6500 W to 7500 W based on a ratio between the first number of rotations and the second number of rotations.
