ABSTRACT:
A converter is specified which is distinguished in that a bus system is provided between the paths of a phase module of the converter and allows potential chambers to be formed around the semiconductor switches and/or the circuitry elements. The potential chambers surround the semiconductor switches and the circuitry elements. They comprise two longitudinal metal sheets which are arranged to be insulated from one another, in particular overlapping. In addition, transverse metal sheets may be provided, which are connected to the connections of the semiconductor switches and/or circuitry elements. The potential chambers result in each potential chamber having a potential difference which is only a fraction of the intermediate circuit voltage. The bus system carries out the insulation of the high potential difference corresponding to the intermediate circuit voltage.
