Abstract
A converter bridge includes at least two half bridges, which are connected together by bus bars. The bus bars include at least two directly opposite bus bar segments and are arranged mirror symmetrically relative to a median plane in the converter bridge. The directly opposite bus bar segments exhibit a relatively small line cross section. Due to the mirror symmetrical arrangement, a high frequency secondary current component, which flows in the opposite direction and belongs to the current flowing through the bus bars, is concentrated in the directly opposite segments of the bus bar and is damped effectively via the relatively small line cross section. In contrast, the low frequency main current component flows in essence uniformly distributed over the profile of the bus bar.
