摘要：
An induction heating apparatus includes a working coil; an inverter configured to perform switching operation to thereby apply a resonance current to the working coil; and a controller configured to provide a control signal with a fixed frequency to the inverter to thereby control the switching operation. The controller changes a pulse width of the control signal based on a predetermined cycle that is set based on a temperature of the inverter.
