ABSTRACT:
A power rectifier arrangement comprises at least one heat sink and at least one power rectifier. The housing floor of the power rectifier is at least partially designed as the input terminal. The secondary winding of the transformer is designed as a ribbon. The power rectifier serves as a fastening element which is screwed to the heat sink and with which the end of the ribbon is pinched between the housing floor and the heat sink. In case at least two power rectifiers are connected in parallel, the ribbon exhibits a plurality of superimposed, electrically-conductive layers corresponding to the plurality of power rectifiers and each of the electrically conductive layers is respectively connected to one power rectifier. An electrically-insulating and thermally-conductive layer is provided between two electrically-conductive layers. Advantageously, the heat sources which are formed by the transformer and the power rectifier are connected in parallel and, therefore, the heat is respectively directly dissipated to the heat sink.
