摘要：This work carried out on improving power purity of Unified Power Quality Conditioner added to Photovoltaic unit. This effort describes the unified power quality conditioner formation and elaborates concept unreformed voltage outline of a distribution system. This practice brings out a complex alignment of UPQC that comprise a DC/DC converter, to support the converter a Photovoltaic unit is used at the DC link. This study used for discriminating between before and after injection, the amount of THD will be changed to a good value and source voltages are sinusoidal. In this described about result of UPQC giving excellent THD with of photovoltaic energy. The execution analysis presents the THD of Photovoltaic source. The working of the presented design is formulated and simulated in MATLAB workspace.
