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) and Radio Frequency Interference (RFI). The IH system generates a considerable amount of high-frequency harmonics because of a myriad of 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 for a three level inverter based SAF for EMI and RFI suppression. A new modeling approach for 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 necessity 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 at 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.
