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.

基于磁滞控制器的Vienna整流器感应加热系统电能质量改善

摘要—感应加热 (IH) 技术越来越多地应用于现代家庭、工业和医疗应用中。现代 IH 系统的设计结合了高频 (HF) 谐振转换器，从而产生 HF 谐波。HF 谐波具有向供电侧回流的固有趋势，并降低电网侧的电能质量。因此，为了缓解这种电能质量问题，已经提出了基于单相维也纳整流器 (1-ø VR) 的 IH 系统。在建议的 IH 系统中采用了滞后和脉冲密度调制控制器。VR 的单向特性保护整个 IH 系统免受 HF 谐波的影响。VR 还提高了输入电源的功率因数，同时降低了输入电流的总谐波失真。通过 MATLAB/Simulink 环境验证了所提出的 IH 系统的可行性。最后，开发了一个 1200 W 的实验原型，并进一步与仿真结果相关联，以验证所提出的 IH 系统的唯一性。
