The invention relates to a charging system (1) for the joint charging of a plurality of batteries (B1, B2,..., Bn). In order to increase the efficiency of such charging systems, a common, preferably unregulated, DC voltage source (4) is provided for all the batteries, which source (4) supplies a busbar (3). An in-phase regulator (21, 22, ..., 2n) is connected to the busbar (3) for each battery (B1, B2, ..., Bn), which in-phase regulator connects the batteries (B1, B2, ..., Bn) to the busbar corresponding to the requirement for an optimum charge state. In this case, the in-phase regulators (2) have a reverse-parallel or commutating circuit (5) consisting of reverse-conducting thyristors (6, 7). This reverse-parallel circuit (5) is operated in a pulse-duration-modulated manner. <IMAGE> |
