Title

QUASI Z SOURCE INVERTER BASED THREE PHASE PV SYSTEM WITH DFRS CONTROL FOR GRID CONNECTED SYSTEMS

Download Paper

Abstract

Grid connected three phase photovoltaic system is affected by the double frequency power mismatch between the dc input and ac output. The double frequency ripple energy has to be buffered by the passive impedance network. Otherwise, the ripple energy will flow into the input side and adversely affect the PV energy harvest. As electrolytic capacitors have high capacitance property which are used to buffer the DFR energy. But for a PV inverter it is found that electrolytic capacitors are considered to be one of the most failure prone components. In this paper, a capacitance reduction control strategy is proposed to buffer the DFR energy in the grid connected three phase quasi Z source inverter applications. The proposed control strategy can extremely reduce the capacitance requirement and achieve low input voltage DFR. So we can prefer highly reliable film capacitors. The increased switching device voltage stress and power loss due to the proposed control strategy is also analyzed. The MATLAB/Simulink platform is used for simulation study and analysis.

Key Words

DC-link voltage balance, Zero voltage switching, Renewable Energy (RE).
