ENERGY STORAGE ARRANGEMENT

摘要

The invention relates, inter alia, to an energy storage arrangement (10) that comprises at least one series circuit (200) having at least two submodules (220) connected in series and one inductor, at least one of the submodules (220) of one or more of the series circuits (200) comprising an input module (221) and a storage module (223) that has at least one electrical energy store. According to the invention, a pole-changer module (222) is electrically connected between the input module (221) and the storage module (223), and can be operated in a normal operating mode and in a polarity changer operating mode. When in the normal operating mode, said pole-changer module (222) applies, to said storage module, the output voltage of the input module (221) at the same polarity as the output voltage of the storage module (223) and, when in the polarity changer operating mode, the pole-changer module (222) applies, to said storage module, the output voltage of the input module (221) at the inverse polarity to that of the output voltage of the storage module (223).
