Abstract: This paper deals with a three-level Neutral Point Clamped (NPC) rectifier-based midpoint converter-fed Switched Reluctance Motor (SRM) drive. The three-level NPC rectifier for midpoint converter-fed SRM drive is used for improving power quality at AC mains and to balance the DC link capacitor voltages. The proposed three-level NPC rectifier is designed, modelled and its performance simulated using MATLAB/Simulink environment. The performance of proposed three-level NPC rectifier-based midpoint converter-fed SRM drive is compared with a six-pulse bridge converter-fed SRM drive to demonstrate its improved power quality.

Keywords: midpoint converter; power quality; switched reluctance motors; neutral point clamped; NPC rectifiers; carrier-based pulse width modulation; AC mains; DC link capacitor voltages; simulation.
