摘要： An electrical generator is connected with a first end of DC/DC converter and an electric storage section is connected with a second end of the converter. An output voltage detecting circuit is connected to the electrical generator, and a control circuit is connected to both the DC/DC converter and the output voltage detecting circuit. The electrical generator raises an adjusting voltage Va at an output terminal to a first predetermined output voltage Vdc1 at a timing when regenerated electric power is produced. Control circuit 35 controls an output voltage Vd to be a lower control voltage Vdk which is lower than the first predetermined output voltage Vdc1. The lower control voltage Vd is set at a value which allows a main power supply to be charged maximally with the regenerated electric power.

摘要： An in-vehicle power supply device includes an electric generator, a main power supply, a DC/DC converter, a power storage unit connected with the electric generator via the DC/DC converter, and a controller for controlling the DC/DC converter. The DC/DC converter is operable to store, in the power storage unit, regenerative electric power generated by the electric generator, and to discharge the stored regenerative electric power from the power storage unit to the main power supply and the load. The controller is operable to stop the DC/DC converter when a charging-status value indicating a charging status of the power storage unit is not larger than a predetermined lower limit value. The controller is operable to activate the DC/DC converter when the charging-status value is larger than the lower limit value and the vehicle ends deceleration. The controller is operable to activate the DC/DC converter when a speed of the vehicle is not lower than a predetermined speed and an accelerator position of the engine is not larger than a predetermined accelerator position even if the charging-status value is not larger than the predetermined lower limit value. The in-vehicle power supply device is capable of reducing power consumption of the DC/DC converter, with the recovery efficiency of the regenerative electric power being held, thereby resulting in a higher efficiency of the device.

The DC/DC converter stores regenerative electric power generated by the electric generator, and discharges the stored regenerative electric power to the main power supply and the load. The controller stops the DC/DC converter when a charging-status value is not larger than a predetermined lower limit value. Additionally, the controller activates the DC/DC converter when the charging-status value is larger than the lower limit value and the vehicle ends deceleration; and activates the DC/DC converter when a speed of the vehicle is not lower than a predetermined speed and an accelerator position of the engine is not larger than a predetermined accelerator position even if the charging-status value is not larger than the predetermined lower limit value.

摘要： A DC-DC converter includes a control circuit which can change the target voltage of the reference voltage source. At the start-up of the DC-DC converter, the PWM control circuit controls so that the first switching element gradually increases the on-off ratio from a minimum on-off ratio; that the second switching element is placed in the OFF state, and that the target voltage is set higher than the normal operating voltage. When the start-up operation is completed, the PWM control circuit controls so that the second switching element starts to turn on and off, and that the target voltage is returned to the normal operating voltage.
