Closed loop speed controlled two stage PFC converter fed PMSM drive

摘要

This paper presents the closed loop controlled two stage PFC (Power Factor Correction) converter fed PMSM (Permanent Magnet Synchronous Motor) drive. The proposed PFC converters consist of uncontrolled rectifier, PFC converter and DC converter. The π filter is connected at the output of converter to reduce output ripple of DC converter. The performance of the proposed converter is verified by interfacing inverter and PMSM drive. This work deals with comparison of PI & FL controlled two stage PFC converter fed PMSM drive system. The steady state performance parameters like output voltage ripple, speed, power factor, THD are analyzed with PI (Proportional Integrative) and Fuzzy Logic Controller(FLC). The Transient parameters such as rise time, peak time, settling time, and steady state error also compared for both controller. The Closed loop PI & FL controlled two stage PFC converter Fed PMSM drive systems are modeled and simulated.
