A rectifier for rectifying alternating current into direct current is described, in which a three-phase generator includes a three-phase stator winding. The phases of the stator winding are triggered via switching elements of a power circuit. The power circuit is controlled via a control part, which includes a controller component. The rectifier includes a control part (control module) having control terminals and a power circuit (power module) controlled by the control module and optionally provided with a cooling device, in which all the power-conducting components are designed as power MOS components and integrated in a stacked construction.

Active rectifier module for three-phase generators of vehicles

A method of establishing an electric connection between electric terminals of a semiconductor component as part of an electric module and additional parts of the electric module by using a punched grid having internal terminal ends and external terminal ends that are electrically connected to the internal terminal ends by metal strip conductors, the semiconductor component and the punched grid are joined so that at least two electric terminals of the semiconductor component are positioned on corresponding internal terminal ends so that a slip-proof mounting of the semiconductor component on the two internal terminal ends is then possible, this mechanical mounting at the same time establishing an electric connection between the electric terminals of the semiconductor component and the internal terminal ends, whereby a metal strip grid, e.g., a punched grid, which, even before being joined to the semiconductor component, has already been embedded on at least one side in at least one partial area in a material that is not electrically conductive, is used as the metal strip grid. This procedure is used for bond-free contacting of semiconductor components for high-power applications in which a power loss of more than 1 Watt may occur.

Method for electrically connecting a semiconductor component to an electrical subassembly

A controller and rectifier for an electrical machine, in particular a three-phase generator for motor vehicles, is proposed in which the controller () and the rectifier () are embodied as an one-piece module ().

Controller and rectifier for an electrical machine, and electrical machine

A cooling device for semiconductor modules having: a cooler bar for accommodating at least one, particularly actively cooled semiconductor module; at least one first channel, particularly a bore hole, in the cooler bar for the passage of a, in particular, liquid coolant; and at least one second channel, particularly a bore hole, in the cooler bar for the feeding and/or return of the coolant to/from the semiconductor module.

Cooling device for semiconductor modules

The invention relates to an apparatus for regulating the exciter current for a rotary-current generator. It has a voltage source, a rectifier, three phase windings, an evaluation unit, and a voltage regulator. The evaluation unit has three input terminals, and each of these input terminals is connected to one of the phase windings. The evaluation unit is intended for evaluating the phase voltages derived from the three phase windings, in order to detect error functions of the rectifier and/or of the phase windings. If such unauthorized work states are detected, then via the voltage regulator, the exciter current flowing through the exciter winding is reduced.
