SVPWM Control Based Bridgeless PFC Cuk Converter for PMSM under Dynamic Conditions
Authors: ,
Abstract: The widely used converter models in most of the power electronics and power system applications are the DC-DC converter models. Increase in switching losses has been observed in Conventional Diode Bridge Rectifier (DBR) and hence the researchers are more focused towards bridgeless converters. The design of a novel bridgeless cuk converter model with buck mode operation is focused in this work. In this converter model, four different modes of operations with two modes in positive cycle (switch ON and OFF condition) and two modes in negative cycles with (switch ON and OFF condition) were analyzed. The design of cuk converter with outer voltage control and inner current control integrated with the Power Factor Correction (PFC) analysis is also dealt in this study. Integration of Permanent Magnet Synchronous Motor (PMSM) load and Sensorless Space Vector Pulse Width Modulation (SVPWM) vector with this design is also proposed to control the PMSM. The performance is analyzed for load varying and speed varying conditions using MATLAB and the results are simulated. The results showed that the proposed system provides significant results with cost effective components utilities.
