CIRCUIT ARRANGEMENTS FOR REDUCING POTENTIAL-INDUCED DEGRADATION IN PHOTOVOLTAICS MODULES

摘要

The invention relates to circuit arrangements for reducing the potential-induced degradation in photovoltaic modules of a photovoltaic generator having an insulation monitoring device for continuous-time insulation monitoring of the photovoltaic generator. Furthermore, the invention relates to a photovoltaic system with a circuit arrangement for reducing the potential-induced degradation in photovoltaic modules, which has a photovoltaic generator and an insulation monitoring device for continuous insulation monitoring of the photovoltaic generator. Different solutions are shown which allow a reduction of the potential-induced degradation with simultaneous continuous insulation monitoring. The circuit arrangements according to the invention are based on the interaction of an insulation monitoring device with circuitry measures for influencing the potential of a photovoltaic module.
