A Three Switch Resonant Inverter for Multiple Load Induction Heating Applications

Abstract

Induction heating (IH) is a trending technology in the domestic applications due to its advantages related to high efficiency, better control, and fast heating. Present research focuses on developing cost-effective and highly efficient solutions. In this article, a three-switch inverter (3SI) for multiple load IH appli cations is proposed, which meets previous requirements. Reduced component count and high efficiency are the key benefits of the proposed inverter. Asymmetric duty cycle control is used to obtain independent control over two loads simultaneously. The operation of the proposed 3SI has been verified by rigorous simulations in Orcad PSpice software and by experimenting with designed hardware prototype. The simulation and experimental results are in good agreement with each other, proving the proposed 3SI as a feasible solution for multiple load IH applications.
