Abstract
A rectifier arrangement for a three-phase generator having at least one power diode allocated to each half-wave of each phase and a cooling arrangement for the power diodes. The power diodes may be designed as diode chips and be arranged between two diametrically opposed heat sinks, while being oriented with respect to polarity and electrically and/or thermally conductive.
Claims14
A rectifier arrangement for a three-phase generator comprising:
- at least one conductive power diode allocated to each half-wave of each phase of the three-phase generator, the power diodes being contained on diode chips, the diode chips having a preselected polar orientation;
- and
- a cooling arrangement including a first heat sink and a second heat sink, the first and second heat sinks being diametrically opposed, diode chips being arranged between the first heat sink and the second heat sink;
- wherein the diode chips are at least one of electrically and thermally conductive, wherein diode chips arranged on a surface of the first heat sink have the same orientation and are arranged directly opposite and electrically isolated from the second heat sink, and wherein, along a preselected axis perpendicular to the surface of the first heat sink, only one of the diode chips is arranged.
