Vector controlled PMSM drive with power factor correction using zeta converter

In this project a PMSM drive with power factor correction (PFC) for a wide range of speed control and low power applications is introduced. This paper deals with the analysis, design and implementation of an AC-DC Zeta converter in discontinuous current mode (DCM) of operation used for power quality improvement at AC mains in vector controlled permanent magnet synchronous motor (PMSM) drives. A PFC based Zeta converter operating in discontinuous conduction mode (DCM) is used for controlling the DC link voltage of the voltage source inverter (VSI) with inherent PFC at AC mains using single voltage sensor. The drive is implemented to achieve power factor at AC mains for a wide range of speed control and supply voltage fluctuations. A MATLAB/ Simulink environment is used to simulate the developed model to achieve a wide range of speed control with high (PF) Power Factor and improved (PQ) Power Quality at the supply. An improved power quality is achieved, with power quality indices within limits of IEC 61000-3-2 standard.
