ABSTRACT:
The module (M.sub.1, M.sub.2, . . ) has a first power-electronics assembly (4) which is at high voltage, a second power-electronics assembly (6) which is at a lower potential, and a transformer (5) which couples the two assemblies (4, 6) forming a DC isolation point. The first assembly (4) and electrical connections (26, 27) of the transformer (5) which are connected to it are arranged in a dielectric material housing (10) which is normally designed in a cuboid shape. The dielectric material housing (10) in each case has an electrically conductive layer, which is connected to frame or ground potential, on its top surface (11) and bottom surface (12) as well as on its front face (13) which is closed at the front. An electrical connection of the first power-electronics assembly (4) is passed through each of the two side surfaces (14, 15) of the module. This module is preferably used to construct a circuit arrangement which is contained in a drive for a railroad vehicle and is of modular construction, and is distinguished by compact construction, a high power transmission capability and the ability to be replaced easily.
