Abstract:
1. An accumulator for charging and discharging electrical energy via an electrical consumer having an input capacitance, comprising: a first accumulator line and a second accumulator line, each of which have a positive pole and a negative pole for charging and discharging the electrical energy; a connecting circuit connected in parallel to, and between, the first and second accumulator lines for parallel-connecting the first accumulator line to the second accumulator line, the connecting circuit including: at least one first switch for disconnecting and connecting the positive poles of the two accumulator lines, at least one second switch for disconnecting and connecting the negative poles of the two accumulator lines, and a bidirectional flyback converter including a transformer; and a protective switching device positioned between the parallel-connected accumulator lines and the electrical consumer for selectively connecting and disconnecting the electrical consumer to the parallel-connected accumulator lines, wherein the protective switching device includes: a third switch for selectively connecting and disconnecting the positive pole of the electrical consumer from the positive poles of the two accumulator lines, and a fourth switch for selectively connecting and disconnecting the negative pole of the electrical consumer from the negative poles of the two accumulator lines.
