Analysis and simulation of quasi-resonant inverter for induction heating applications

Abstract

In the last years, induction heating systems have gained a big growing in the home appliances market. The following work proposes to design an induction cooking heating system. The power transfer process will be optimized by limiting or even eliminating switching losses using techniques such as zero current/voltage switching and by designing a parallel LC resonant circuit, which operates near at the resonant frequency. The paper will present a simulation and a design method for such type of converters, with an and without implementation of zero current switching algorithm.
