A Single Stage Power Factor Correction Converter Fed VSI Based PMBLDC Motor Drive

Abstract

This study introduces an innovative method to improve the effectiveness of Permanent Magnet Brushless DC Motor (PMBLDCM) systems by using a Single-Stage Power Factor Correction (PFC) converter. The suggested system employs a buck half-bridge DC-DC converter as a PFC converter to enhance power quality and regulate the voltage source inverter (VSI) that supplies PMBLDC motor. The PFC converter's front end consists of a diode bridge rectifier (DBR) that is coupled to a single-phase AC main. Therefore, the VSI functions just as an electrical switch for the PMBLDC motor, leading to energy-efficient operation. In addition, this study expands the inquiry by examining the utilization of fuzzy logic controller (FLC) in the suggested drive system. This research investigates the effectiveness of FLC in improving the performance of PMBLDC motor drives, which are often used in complex and nonlinear systems, unlike traditional applications. FLC are examined for their capacity to manage indeterminate system behaviors, hence enhancing control strategies that are more precise and dependable. The findings of the comprehensive investigation illustrate the adaptability and efficacy of FLC in enhancing the efficiency of the suggested drive system over a broad spectrum of speeds and input AC voltages. The results highlight the capability of this integrated method in attaining exceptional efficiency and energy preservation in PMBLDC motor drives.
