CONTINUOUS VOLTAGE TAKING DEVICE FOR ENERGY STORAGE FACILITY AND METHOD FOR GENERATING CONTINUOUS VOLTAGE FROM ENERGY STORAGE FACILITY

摘要

DC voltage-taking device (8) for an energy storage installation (1) having supply branches (Z) with storage modules (3) for generating an AC voltage on output terminals (1a, 1b, 1c), a first half-bridge arrangement (9) has first collector terminals (8a, 8b, 8c) connected to the output terminals (1a, 1b, 1c), and a second half-bridge arrangement (15 ) has second collector terminals (8g, 8h, 8i) coupled to the output terminals (1a, 1b, 1c). A voltage pickup (14) is coupled between the first (9) and the second half-bridge arrangement (15) and, depending on the potential difference between these assemblies (9) and (15), provides a DC voltage (UZK) on the output terminals (8e, 8f) of the device (8).
