    摘要: The invention intends to reduce the inductance of wirings for connecting an electrolytic capacitor for use in a low-voltage electric device, and realizes to suppress the surge voltage and improve the frequency response. For a low-voltage electrolytic capacitor, the anode and cathode electrode terminals (2) are placed to come close, and broad parallel plates (4) are used for the wirings connecting to the electric device (3), so that the to-and-fro currents overlap in an area of the power wirings near the electrolytic capacitor, thereby reducing the inductance of the wiring parts to a large extent.

    摘要: The present invention relates to an apparatus for effectively reducing vibrations of a vehicle engine and the vehicle body due to irregular combustion of the engine. In the inventive vibration suppressing apparatus, a generator (4) is provided which has a voltage regulator (9) to control a field winding (8) current so as to output a constant voltage to a battery (1). When irregular combustion of the engine is detected on the basis of a change in the engine speed, a voltage higher than the output voltage of the generator (4) is applied across the field winding (8) to increase the load torque on the generator (4). A change in the load torque of the generator (4) induces vibrations on the generator body due to reaction. When the generator vibrations and vibrations due to irregular combustion are in inverse phase relationship to each other, they are cancelled by each other to suppress those vibrations.

    摘要: A power supply system for a motor vehicle includes a battery (2) of high voltage for a load system (3) rated at 48 V and a high-voltage generator (1) for charging the battery. Loads rated at high voltage is supplied with electric power directly from the battery. A power MOS IC element (41) connected in parallel with the battery is controlled in respect to the duty factor for producing at the output terminal thereof a low voltage of 24 V or 12 V on an average, wherein low-­voltage loads (5, 6) are controlled by the low output voltage.
