Abstract
The rectifier arrangement, preferably for a three-phase generator for a motor vehicle, has at least one power diode of positive polarity and at least one power diode of negative polarity assigned to respective half waves of each phase of the three-phase current and a cooling arrangement for the power diodes, the power diodes of like polarity being arranged on respective heat sinks in an electrically and thermally conductive fashion, and the heat sinks being sandwiched together with at least one electrically insulating part (32) which contains the electrical conductors between the diodes and the three-phase winding. The electrically conductive connections of the power diodes (12, 14) of positive and negative polarity to the phases (U, V, W) of the three-phase generator extend within the electrically insulating part (32) so that electrical contact is made with the power diodes (12, 14) of positive and negative polarities in respective cavities (40, 44) in the insulating part (32) via in each case one spring element. A punched grid (34) for each of the phases (U, V, W) extends in the cavities and includes conductor tracks (50) and spring elements (48, 49) for making electrical contact between pairs of power diodes of opposite polarity and each phase.
