Novel Performance Analysis of Induction Heater Using Parallel and LLC Resonant Inverter

Induction Heating (IH) applications require high frequency currents which are obtained using resonant converters. Perhaps, high switching frequency of converter debilitates the efficiency of the converter, which is overcome by soft switching. A resonant converter provides most of the energy conversion efficiency in a system by minimizing switching losses; therefore, they are a better choice for IH systems. The aim of this paper is to compare the performance analysis of parallel and LLC resonant inverters for induction heating application.
