Abstract:
A module (M.sub.1, M.sub.2, . . . ) of a circuit arrangement which is preferably contained in a drive for a railroad vehicle and is of modular construction, having 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 first assembly (4) and the second assembly (6) forming a DC isolation point, wherein the first assembly (4) and electrical connections 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, wherein 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, and wherein an electrical connection of the first power-electronics assembly (4) is passed through each of the two side surfaces (14, 15) of the module (M.sub.1, M.sub.2, . . . ).
