成果简介	NOVELTY - A grid-integrated solar photovoltaic (PV) system (100) comprises solar PV unit (200), direct current (DC)-DC boost converter (300), DC-link capacitor (400), 4-leg voltage source inverter (VSI) (500), interfacing inductors (600), nonlinear load (700), dSPACE 1104 controller (900), gate driver circuit (1100), dead-time circuit, and isolation/amplification circuit. The solar PV panels generate DC power, which is then conditioned for integration with the grid. The first stage of power conversion involves a DC-DC converter. The inductors are used to interface the solar inverter with the grid and suppress current ripples that may arise from high frequency switching operation of VSI. The nonlinear load consists of a three-phase diode bridge rectifier (DBR) and a series R-L branch, representing a typical non-linear load condition. The output of the interfacing inductors is connected to the three-phase grid wires at the Point of common coupling (PCC) (800). USE - Grid-integrated solar photovoltaic (PV) system for arc furnaces, static volt-ampere reactive (VAr) systems, inverters for distributed generation, ac phase controllers and power electronic converters. ADVANTAGE - The system enhances the utility power quality (PQ) performance in a grid integrated solar photovoltaic (PV) system through multifunctional voltage source inverter (VSI). DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a grid-integrated solar photovoltaic system. 100Grid-integrated solar photovoltaic system 200Solar photovoltaic unit 300DC-DC boost converter 400DC-Link capacitor 5004-Leg voltage source inverter 600Interfacing inductors 700Nonlinear load 800Point of common coupling 900dSPACE 1104 controller 1100Gate driver circuit
