Photo-voltaic system for refrigeration plants in isolated areas

Abstract

This paper presents design and modeling of quasi resonant ZCS (Zero Current Switching) converter used in standalone PV based PMSM (Permanent Magnet Synchronous Motor) drive used in refrigeration system for remote locations. Solar cooling is an attractive and plentiful in the nature application, due to cooling demand match with the peak incident solar radiation. Three phase vector controlled VSI (Voltage Source Inverter) is employed for supplying the PMSM drive with variation in solar irradiation. MATLAB/SIMULINK environment is used to developed the proposed quasi resonant converter fed standalone PV based PMSM drive. The performance of developed system is investigated under various operating conditions.
