Document Type and Number:
WIPO Patent Application WO/2017/064801
Kind Code:
A1
Abstract:
A power supply system equipped with a power supply control device that converts input commercial power from AC to DC, and supplies the DC power to a load device, wherein a current value detection unit, a power value detection unit, a timekeeping unit, and a storage unit are provided in advance within the power supply control device. The power supply control device sets the power assist starting point to an initial value, obtains various measurement data via the current value detection unit and the power value detection unit, and stores the obtained measurement data in the storage unit in association with time information from the timekeeping unit. Then, the power supply control device checks the elapsed time from the start of power assist on the basis of the time information from the timekeeping unit, and when the elapsed time exceeds a prescribed period of time, the power supply control device evaluates each item of measurement data of the prescribed time associated with the time information stored in the storage unit, and resets the power assist starting point.
