Wechselstromgenerator für Motorfahrzeuge |
摘要 |
An alternating current generator for motor vehicles having an extremely small power loss and which can be simply cooled includes a power converter having at least either high side semiconductor power elements or low side semiconductor elements. The high side power elements connect an output terminal of the armature coil to a high potential terminal of the battery; the low side semiconductor power elements connect an output terminal of the armature coil to a low potential terminal of the battery. The power converter converts the alternating current generated voltage of the armature coil into a direct current voltage to supply electricity to the battery. An exciting current controller includes a switching transistor for controlling an exciting current to a field coil. Either or both all the semiconductor power elements in the power converter or the switching transistor in the exciting current controller is formed of SiC material, which is a compound of Si and C, having a resistivity smaller than that of pure Si. <IMAGE> |
