インダクタを結合した構造を有するIH クッキングヒータ用 時分割制御高周波インバーターの実証評価

抄録

This paper represents the practical evaluations of an improved time-sharing high-frequency resonant soft-switching inverter for all metal induction heating (IH) cooking appliances. By introducing inductor coupling technology, the number of the circuit components and a physical volume of the circuit can be reduced. A design procedure of the coupling inductor is discussed in detail. Furthermore, two IH power regulation sequences; phase shifted PWM and PAM are compared to the viewpoint of the power conversion efficiency.
