Fuzzy Tuned PID Controller Based PFC Converter-Inverter Fed SRM Drive

Abstract

This paper present a comprehensive analysis of current controlled power factor correction (PFC) converter-inverter fed Switched reluctance motor drive with fuzzy gain tuned PID controller. Power electronics equipments are the major source of harmonic pollution of the utility supply and reduce the efficiency and could be avoided by using the techniques presented in this paper. The paper presents the mathematical model and the circuit configuration of PFC that includes a single-phase diode bridge rectifier together with a boost converter, fuzzy tuned PID controller and hysteresis current controller (HCC), which improves the quality of the current drawn from the utility supply. The advantages of the developed system are low harmonic distortion in ac supply currents, nearly unity power factor over a wide operating shaft speed range. The proposed system is modeled including SRM and the simulated performance in MATLAB frame is presented and discussed. Significant reduction of the THD and rms value of the supply current is achieved with the proposed method.
