The disclosure relates to electrical converters. The teachings thereof may be embodied in a circuit assembly for an electrical converter. For example, a circuit assembly for an electrical converter may include a set of switching units, each switching unit comprising a semiconductor switch and a gate driver circuit for controlling the semiconductor switch. The respective semiconductor switch and gate driver circuit of each switching unit are arranged on a common carrier circuit board and are electrically connected to one another by a printed conductor on the carrier circuit board.

Fast-switching circuit assembly for a converter

A battery with simultaneous active compensation of the interference signals occurring during the charging is provided. In order to charge the battery, at least two converters are used, which can control connected loads during the working operation. During the charging operation, one converter controls the charging process while the other converter performs an active compensation of the interference signals that occur.

Charging device for an energy store and method for operating a charging device

The invention relates to a method for selecting network access to one or more data networks by means of a telecommunications terminal. In a first step of said method, network access information, which has been determined by the telecommunications terminal and/or additional telecommunications terminals during network connections established by different network access operations, is analysed. In a second step, network access is selected on the basis of the analysed network access information.
