A Three Phase AC-AC ZCS Resonant Converter for Induction Heating

Generally, domestic induction-heating technology requires a high output power levels with less number of components in a compact size. To satisfy these requirements, the basic circuit configurations are considered based on the combination of a rectifier and a inverter. The main disadvantage of this method has low-efficient and economic problems. This paper proposes a new concept unlike previous method, i.e the direct conversion of ac?ac converter for reducing the component count, reduce cost, improve reliability, and also efficiency. Generally, the proposed converter is a voltage-source based series-resonant converter used for controlling output power, and minimizing the control complexity. This paper also proposes a concept of AC-AC converter based three phase Induction Heating applications.
