摘要: Photovoltaic (PV) source simulators serve as a convenient tool for the dynamic evaluation of solar power conditioning systems and maximum point tracking algorithms. High efficiency fast transient response time are essential features any PV simulator. This paper proposes new type simulator that incorporates advantages both analog digital-based simulators. The proposed system includes three-phase ac-dc dual boost rectifier cascaded with dc-dc interleaved buck converter. selected stage topology is highly reliable efficient. Moreover, multiphase converter helps improve though producing low output ripple which makes it adequate circuitry emulates precisely static characteristics actual generators under different load environmental conditions. Additionally, allows creation partial shading bypass diodes effect on characteristics. investigates performance commercial inverter using in steady-state Closed-loop impedance has been measured verified at operating regions. profile--magnitude phase--matches generators. Mathematical modeling experimental validation thoroughly presented based 2.0 kW hardware prototype. efficiency, including active-front-end stages, peaks 96.7%.
