System for performing voltage conversion for photovoltaic modules, has multiple parallel switched power supply branches connected to phase connectors, where each power supply branch comprises power supply module connected in series

摘要

The system (20) has multiple parallel switched power supply branches (1a-1c) connected to phase connectors (2a, 2b, 2c) of an electrical power supply (2) via an output terminal. Each power supply branch comprises a power supply module (3) connected in series. The power supply branches are connected at junctions between the power supply modules via an interconnection unit (5). The power supply module comprises an energy store device placed parallel to a photovoltaic module (9). A control device (6) is connected to the power supply module. An independent claim is also included for a method for performing voltage conversion for photovoltaic modules.
