Vienna Rectifier with Proposed Synchronous Reference Frame Control Theory for Power Quality

Abstract

In this paper, three phase Vienna rectifier (VR) topology with sinusoidal input currents and controlled output voltage has been compared with various rectifiers. A comparative study of three different rectifiers have been compared with Vienna rectifier by parameters like switching loss, conduction loss, power density etc. Performance of Vienna rectifier with proportional integrating and derivative control method (PID control), Hysteresis control method and fuzzy logic control method have been analyzed here by parameters like Total Harmonics Distortion (THD) and Power factor (PF) along with various Load conditions. First time we have proposed synchronous reference frame (SRF) for control of Vienna rectifier. Results of Simulink model of proposed SRF control theory has been compared with PID control, hysteresis control and fuzzy logic control methods. We have tried to suggest proposed SRF control method is better among them to improve performance of Vienna rectifier.
