Analysis, design and control of single-phase three-level power factor correction rectifier fed switched reluctance motor drive

In this study, a single-phase three-level power factor correction (PFC) rectifier fed switched reluctance motor (SRM) drive is proposed for improving the power quality at ac mains. The asymmetry in the dc-link capacitors voltages of the midpoint converter fed SRM drive is improved by using a single-phase three-level PFC rectifier. This PFC rectifier configuration uses two active semiconductor switches, an inductor and operates as a boost PFC rectifier. The proposed single-phase three-level PFC rectifier fed SRM drive is designed, modelled and its performance is simulated in MATLAB/Simulink. The simulated performance of the proposed single-phase three-level PFC rectifier fed SRM drive is experimentally validated for dc-link capacitors voltage balancing and power quality improvement.
