STATISCHER UMFORMER UND VERFAHREN ZUM ANFAHREN DES UMFORMERS

摘要

#CMT# #/CMT# The static converter has a power converter circuit (10) with multiple module branches. Each module branch has one or multiple electrical bipolar line sub modules which are switched in rows as switchable voltage sources. The device (20) for pre-loading the capacitor, which have power electronic units for providing the adjustable pre-loading current, which is supplied from an auxiliary voltage network (H3). The power electronic units are connected over a pre-loading transformer (21) with the power converter bridge. #CMT# : #/CMT# An independent claim is also included for a method for starting the static converter. #CMT#USE : #/CMT# Static converter. #CMT#ADVANTAGE : #/CMT# The static converter has a power converter circuit with multiple module branches, and thus enables to reach the sufficiently high voltage level for the capacitors of the submodule. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a circuit diagram of a static converter. 10 : Power converter circuit 20 : Device 21 : Pre-loading transformer H3 : Auxiliary voltage network N3 : Three-phase supply network.
