The present patent application relates to a high-voltage motor vehicle electrical system comprising an electrical heating device and at least on further consumer during switching on of which, undesired electromagnetic oscillations may occur in the electrical system. According to the invention, these are suppressed by initially switching on the heating device, before the further consumer is switched on. Switching on the heating device changes the complete impedance of the electrical system such that a resonant enhancement of the interference oscillations is prevented. Preferably, the heating device is switched on only as shortly as possible (only during the switching on process of the further consumer) in order to minimize an undesired heating.

High-voltage motor vehicle electrical system

A power semiconductor module includes at least two interconnected power semiconductor units having actuatable power semiconductors, a module housing in which the power semiconductor units are disposed and which has an electrically insulating side wall, and at least one connection bus extended through the side wall and connected to at least one of the power semiconductor units. High explosion resistance and particularly inexpensive production are provided by forming the insulating side wall as a stack of insulating and partial elements constructed as a single piece, in which contact areas of the partial elements contact each other.

Power semiconductor module having layered insulating side walls

A power semiconductor module for energy distribution, includes at least one power semiconductor, connection terminals for connecting the power semiconductor module, and a housing, in which protection from explosion is ensured in the module even in the event of electric arcs. Therefore, each power semiconductor and each connection terminal is disposed in the housing, and the housing includes an exhaust gas channel for the controlled withdrawal of hot gases and/or plasma in the event of an explosion.
