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

摘要

A continuous voltage tap device (8) for an energy storage installation (1) having a set of supply branches (Z) with a set of storage modules (3) for generating an alternating voltage on a set of output terminals (1a, 1b, 1c). A half-bridge arrangement (9) has a set of collecting terminals (8a, 8b, 8c) respectively connected to one of the output terminals (1a, 1b, 1c), and a reference terminal (8d) is connected to a reference rail (4) of the installation (1). A voltage lifter (14) is installed between the half-bridge (9) and the reference terminal (8d) so that, depending on the potential between the half-bridge (9) and the reference terminal (8), it supplies a DC voltage (U) to the tap terminals (8e, 8f) of the DC tap (8).
