Adaptive Controller for Bridgeless New SEPIC Integrated Landsman Converter for PFC in Induction Motor

Abstract

The Induction Motor (IM)when powered by an AC supply, results in low power factor because of excessive harmonic contents, which is effectively minimized by adopting proper Power Factor Correction (PFC) technique. This paper proposes an AC-DC bridgeless SEPIC-Landsman converter for a 3ϕVoltage Source Inverter (VSI) fed IM to perform effective PFC and power quality enhancement at AC supply mains. Here, the bridgeless SEPIC-Landsman converter’s switching operation is controlled by the adaptive Proportional Integral (PI) controller for getting a controlled DC output voltage with minimum ripples. A Cascaded Type 2 Fuzzy Logic Controller (CT2FLC) effectively controls speed of the IM and also reduces the peak overshoot problem. Here, the speed control is achieved by adjusting voltage and frequency of 3$\mathrm{\varphi }$ IMwith a reduced settling time of 0.2s. The proposed system is modeled with MATLAB Simulink and empirically validated, generating a THD value of 1.69% and an efficiency of 93%. The simulation and hardware results thus obtained confirm an effectiveness and reliable performance of the proposed system.
