摘要： PROBLEM TO BE SOLVED: To provide power supply equipment which have no effect on other systems even in the case of a big power discharge.
SOLUTION: In the power supply equipment 100, a voltage dropper 130 is provided for maintaining a specified voltage in both directions respectively between a battery 110 and a capacitor 120. Consequently, when the engine 200 is rotated and power is generated by a M/G 150, the capacitor 120 is charged at higher voltage than that of the battery 110. In startup of the M/G 150, a big power is instantaneously supplied from the capacitor 120 to the M/G 150, but at this time, power-feed from the battery 110 is not effected until the voltage of the capacitor 120 is sufficiently dropped. As a result, the load connected to the battery 110 is unaffected, and power can be fed stably to other electric systems.

摘要： PROBLEM TO BE SOLVED: To attain a generation control method and a vehicle driving device capable of an electrically stable operation in a voltage range where high efficiency can be obtained. SOLUTION: A required input electric power necessary for an AC motor 20 calculated by a torque output control unit 21 is fed back, using torque requirement information calculated by a rear torque calculator 11 based on vehicle information such as wheel speed and engine revolutions. When a generation target electric power to be generated by a generator 30 is calculated at a generation target electric power calculator 12; the generation target electric power is added or subtracted at a predetermined rate to or from the required input electric power necessary for the drive motor, according to a comparative result between a present actual voltage actually measured by a voltage sensor 40 and a target voltage in generating the generation target electric power. Using the added or subtracted value, a generation operation command is issued from a generation control unit 13 to the generator 30. This allows the generator to operate so that the actual voltage meets the target voltage, and finally the target voltage works to generate electric power satisfying the required input electric power.

摘要： PROBLEM TO BE SOLVED: To provide an idle stop controlling device to effect proper re-start of an engine and exert no influence on other electric system by effectively using the power of a capacitor. SOLUTION: The idle stop controlling device is provided with an inverter 140; and a switch unit 120 having a switch 121 and a diode 122 situated between the positive electrodes of a capacitor 130 and a battery 110. In a diode 122, a direction extending from a battery 110 to the capacitor 130 is set as a forward direction. In case of switching to idle stop, the switch 121 is opened, the battery 110 is electrically cut off, a power is generated at a relatively high voltage by the inverter 140 and only the capacitor 130 is charged therewith. Since, during starting of an engine, a high voltage power is supplied from the capacitor 130 to an inverter 140, an engine 200 is smoothly started. Even when discharge of the capacitor 130 is progressed and an output voltage comes to the output voltage of the battery 110, only when the engine 200 is not started, a power is supplied from the battery 110 to the inverter 140.
