Abstract
—Induction heating (IH) technology is increasingly implemented in domestic, industrial as well as medical applications in the modern era. Designing of modern IH system incorporates high frequency (HF) resonant converter that results in the generation of HF harmonics. The HF harmonics has an inherent tendency to back flow toward the supply side and deteriorates the power quality at the grid side. So, in order to mitigate this power quality issue, a single phase Vienna rectifier (1-ø VR) based IH system has been proposed. Hysteresis and pulse density modulation controller is employed in the proposed IH system. The unidirectional nature of VR protects the overall IH system from the HF harmonics. VR also improves the power factor of the input supply along with low total harmonic distortion of input current. The feasibility of the proposed IH system is validated through MATLAB/Simulink environment. Finally, an experimental prototype of 1200 W has been developed and further correlated with the simulation results to verify the uniqueness of the proposed IH system.
