    The induction heating is widely used not only in the industrial fields but also in the home appliances. But the conventional induction heating systems have shortcoming that it use only magnetic utensil. In this paper, heating of Aluminum sheet by full-bridge series resonant high-frequency inverter is proposed. Also, the principle of induction heating and operations of full-bridge inverter equivalent circuit are explained. The proposed inverter controls the output voltage using phase-shift irrespective of the switching frequency using phase-shift. The proposed circuit is generally analyzed by using the normalized parameters. Also, the characteristics for operation are estimated according to the parameters, such as switching frequency, the variation of phase angle(β) of phase-shift. In the experiment Maximum efficiency increases to 70% in the proposed induction heating system, and the results of several characteristics are analyzed by pspice's simulation. It is confirmed that the experimental waveforms are similar to theoretical ones. As a result, the proposed induction heating system by full-bridge resonant inverter shows the possibility that make up for the shortcoming of the conventional existing induction heating systems.
