The aim of the work is the investigation of induction heating system used for longitudinal, high frequency pipe welding.Coupled electromagnetic and temperature field distribution has been studied in order to estimate system efficiency and factors influencing the quality of the welding process and required energy. The problem was considered as three dimensional. Time harmonic electromagnetic and transient thermal field has been solved using finite element method and COMSOL 4.2 software package.

Induction Heating System

This paper propounds the incorporation of a three-level inverter based Shunt Active Filter (SAF) in the Induction Heating (IH) system to eradicate the problems due to Electromagnetic Interference (EMI) & Radio Frequency Interference (RFI). The IH system generates a considerable amount of high-frequency harmonics because of myriad causes, the predominant one being the high-frequency switching in the resonant inverter. The former has an immanent propensity to flow towards the supply side and results in the enfeeblement of power quality. Moreover, in the present work, attention has been paid off to develop a proper control strategy of a three level inverter based SAF for EMI and RFI suppression. A new modeling approach of three-level inverter based SAF is proposed and the efficacy and viability of the proposed controllers for SAF in the IH system are validated via simulations in PSIM. A comparative analysis of THD in the input current waveform has been done to advocate the desideratum of SAF as an imperative part of the IH system. Results obtained by simulations show that the proposed approach is more effective than the reviewed approaches on compensating the harmonic currents and thus, the filtering action of SAF is able to achieve the THD of input current within the limit specified by the IEEE-519 standard. Doi: 10.28991/HIJ-2021-02-03-08 Full Text: PDF
