چکیده
136 Abstract— This paper presents a single-phase, single-stage current source inverter (CSI) based photovoltaic system (PV) for grid connection. A double-tuned parallel resonant circuit is designed to attenuate the secondand fourthorder harmonics at the inverter dc side. It helps to improve the power quality and system efficiency. A modified carrier based modulation technique for the current source inverter is studied to magnetize the dc-link inductor and to control the switching pattern for the single phase grid-connected CSI. The operation of Single Phase Transformer-less grid connected PV system is verified by the simulation using MATLAB/Simulink software. The results are analyzed and presented.

Power decoupling of pulsating grid side power from constant source side power is one of the paramount issues in single phase-phase grid-connected renewable systems. The principal aim of such systems is the decrease of the capacitance of the decoupled capacitor. However, this causes some problems such as an increase in the total harmonic distortion (THD) of injected current to the grid and bus v...
