AC-DC Cuk Converter for Power Quality Improvement of Vector Controlled PMSM Drive

Abstract

This paper deals with the analysis, design and digital signal processor (DSP) based hardware implementation of a high frequency isolated AC-DC Cuk converter in discontinuous current mode (DCM) of operation used for power quality improvement at AC mains in vector controlled permanent magnet synchronous motor (PMSM) drive. The design of the Cuk converter is presented to feed the voltage source inverter (VSI) of a vector controlled PMSM drive system. Modeling and simulation is carried out in a standard PSIM software environment. Test results are obtained on DSP based hardware implemented AC-DC Cuk converter fed PMSM drive to demonstrate the improvement in the power quality at AC mains.

Indexing terms:

• Power quality
• High frequency isolation
• Total harmonic distortion
• Digital signal processor
• Cuk converter
• Vector control
• Permanent magnet synchronous motor
