Power Quality Improvement in a PMBLDCM Drive Using a forward Buck Converter
      T.Venkateswara Rao, B.Mahesh Babu
Abstract: Solid-state switch-mode rectification converters have reached a matured level for improving power quality in terms of power-factor correction (PFC), reduced total harmonic distortion at input ac mains and precisely regulated dc output in buck, boost, buck–boost and multilevel modes with unidirectional and bidirectional power flow. In this paper, an improved power quality converter employing conventional PI based & intelligence controlled( FLC) forward buck converter topology is used to feed a permanent magnet brushless DC motor (PMBLDCM) drive. Normally, the PMBLDCM drive consists of a three-phase voltage source inverter (VSI) and a PMBLDCM which is fed from single-phase AC mains through a diode bridge rectifier (DBR). In this proposed system a conventional pi and fuzzy logic controlled based forward buck DC-DC converter is used after the DBR and it performs power factor correction (PFC) at input AC mains and voltage control at DC link, in a single-stage.
