A Single-Coil Multi-Tapped PDM-Based Induction Heating System for Domestic Applications

The conventional heating system is inefficient as the major part of coil lies out-side vessel it placed on. This research article proposes a new single-coil multi-tapped induction system. novel facilitated by half-bridge resonant converter controlled zero-voltage switching (ZVS). multi-tapping winding ensures an effective heat transfer between and working with windings segmented to equivalent size vessel. pulse density modulation (PDM) scheme employed here control proves be most versatile one. whole duly simulated for 850 W IH setup in MATLAB Simulink implemented hardware prototype using converter. pulses are developed through PDM PIC16F877A controller. simulation experimental results prove credibility proposed (IH) scheme, during heavy loading conditions, outperforms gaining efficiency 89.29%
