Switch for the Optimization of Module Power by Reconfiguration of All Strings (SOMBRA): An Insulated Integrated Switch for a Reconfigurable Solar Panel

摘要: The energy yield of a solar panel can be severely impacted by partial shading. Shade caused nearby static objects hardly avoided in installations such as building-applied or building-integrated photovoltaics. Smart reconfigurable photovoltaics (PV) panels are able to change their intra-module configuration reduce this impact: small substrings rewired connected more optimal configuration. To achieve this, reconfiguration switch needs designed. In paper for the optimization module power all strings (SOMBRA), smart switch, is presented. SOMBRA fully integrated, low-ohmic designed currents up 10 A. It floating 50 V, while still being communicate with central unit an inter-integrated circuit (I 2 C) slave. Two versions were realized, SOMBRA-LV10 low voltages (LV) and load current A, SOMBRA-HV05 high (HV) 5 Measurements proved these devices functional, measuring on-resistance 1.3 m Ω 7.3 SOMBRA-HV05. This will elaborate on operation, design, implementation SOMRBA, well first tests PV module.
