MODULAR MULTI-STEP CONVERTER, AND METHOD FOR OPERATING A MODULAR MULTI-STEP CONVERTER

摘要

The invention relates to a modular multi-step converter (2, 56) comprising a series circuit (4) of a plurality of modules (6). In order to be able to provide a cost-effective modular multi-step converter (2, 56), according to the invention, each of the modules (6) comprises a plurality of sub-modules (14, 44, 58) that are connected in parallel, and each of the sub-modules (14, 44, 58) includes a switching device (16), an energy store (18) and a choke element (20).
