Abstract
An induction heating cooker has many advantages. It is safe, clean, easy operation and highly efficient, because it heats a metal pan directly by electromagnetic induction phenomena.
But the conventional induction heating cooker has demerit of unheating the aluminum pans. Because they have low resistivity and are a non-magnetic material. This demerit is an obstacle for market penetration.
This paper reports the induction heating cooker for aluminum pans that was achieved heating efficiency 63%, which was developed by the low heat loss exciting coil under high frequency current and a single ended push-pull (SEPP) resonant inverter using IGBT.
