Abstract (en)
[origin: WO2011060823A1] The invention relates to a submodule (13) for charging or discharging an energy store (22), comprising a capacitor unit (14) and a power semiconductor circuit (15) having power semiconductors (16, 17) that can be switched on and off, wherein the capacitor unit (14) and power semiconductor circuit (15) are connected to each other such that, after actuating the power semiconductors (16, 17) of the power semiconductor circuit (15), at least the voltage released at the capacitor unit (14) or a zero voltage can be produced at output terminals (19, 20) of the submodule (13). In order to provide such a submodule which allows individual adaptation of the charging operation to the requirements of the particular energy store and which, furthermore, is cost-effective, according to the invention the energy store (22) can be connected to the submodule (13) via a DC-DC regulator (21). The DC-DC regulator (21) is connected to the capacitor unit (14) and is designed to convert a capacitor voltage (Uc) released at the capacitor unit (14) into a charge voltage (UL) that is required for charging the energy store (22), and to convert a discharge voltage (EL) released at the energy store (22) during discharge into the capacitor voltage (UC).
