    摘要: A generating apparatus for a vehicle is composed of an AC generator (1), a battery (7) and a rectifying bridge circuit (3. The bridge circuit (3) is composed of high-side elements (31, 32, 33) and low-side elements (34, 35, 36). One of the low-side rectifying elements (31, 32, 33) which is connected to an armature coil generating the giant-pulse-voltage is turned on to circulate the giant-pulse-voltage in the armature coils (11, 12,13), thereby suppressing the giant-pulse-voltage.

    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.

    摘要: A vehicular generator motor performing generator operation and motor operation is disclosed. The generator motor comprises an AC-DC converter means and a switching means. The converter means is composed of a plurality of MOSFETs and connected between each armature coil and a vehicular storage battery. Alternating current produced across the coils is converted into a direct current for charging the battery by the AC-DC converter means in generator operation mode. In motor operation mode, the DC output from the battery is converted into an alternating current for setting up a rotating magnetic field by the converter means, and the battery output is fed to the armature coils. The mode of operation of the MOSFETs is switched between these two modes by the switching means. The rotating field produces a certain phase difference with the magnetic field developed by the rotating magnetic poles. The MOSFETs are made of SiC having a smaller resistivity than that of Si. This ensures a high withstand voltage necessary during power generation. Loss caused by large current flowing in the motor operation mode is reduced. Good driving torque can be obtained.

    摘要: Battery voltage is compared by a comparator (16) with a reference level so that when the voltage of the normally charged battery (6) becomes higher than a normal reference voltage, it is regulated as high as the normal reference voltage. When an average value of the battery voltages in a period, in which a typical operating speed of the engine is included, becomes higher than an upper level V1, the reference voltage is lowered. On the other hand, when the average of the battery voltages in such period becomes lower than a lower level V2, the reference voltage is increased.
