Simulation and analysis of current controlled PFC converter-inverter fed SRM drive

Switch reluctance motor (SRM) drives are simpler in construction and their combination with power electronic equipments yield an economic solution to its variable speed operation. 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 circuit configuration of power factor correction (PFC) that includes a single-phase diode bridge rectifier together with a boost converter 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
