Title:
ELECTRIC POWER CONTROL DEVICE AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2017/159042
Kind Code:
A1
Abstract:
Provided are a device and the like by which the continuous operation time of a load which uses a capacitor as a main power source can be extended. When a capacitor voltage V1 is equal to or higher than a first reference voltage Vth1, electric power is supplied from a capacitor 11 to an electric motor 14 as a load without going through a boosting operation by a converter 12. Whereas when the discharge capacity of the capacitor 11 has decreased due to the supply of electric power to the motor 14 as the load and the capacitor voltage V1 has dropped lower than the first reference voltage Vth1 as a result, electric power from the capacitor 11 is boosted by the converter 12 before the electric power is supplied to the load.
