    摘要: The power supply apparatus a main power device, an auxiliary power unit, and controlling means. Each of the main power device and the auxiliary power unit is configured to supply DC power to a DC supply line. The main power device is configured to generate DC power by use of power supplied from a secondary cell. The controlling means is configured to, when a measurement (a magnitude of a current flowing through the DC supply line) exceeds an optimal current magnitude, send an instruction to the main power device such that a current supplied from the main power device to the DC supply line has the same magnitude as the optimal current magnitude. The optimal current magnitude is defined as a magnitude of a current supplied to the DC supply line from the main power device operating so as to maximize a proportion of power supplied from the main power device to the DC supply line to the sum of power supplied from the secondary cell to the main power device and loss caused by an internal resistance of the secondary cell. The main power device is configured to adjust the magnitude of the current supplied to the DC supply line on the basis of the instruction received from the controlling means.

    摘要: A DC power distribution system is equipped with a storage device having a first storage battery, which discharges to electrical apparatuses only during power failure, and a second storage battery, which discharges to electrical apparatuses when service is not interrupted. The electricity storage device and electrical apparatuses are supplied with DC power from a power generation device which generates electricity using natural energy, and DC power which has been converted from AC power supplied from a commercial power source. When the power supply from the electricity generation device and the commercial power source is interrupted, the first storage battery discharges power to the electrical apparatuses.

    摘要: A power supply apparatus (10) includes one first power device (30) and a plurality of second power devices (41, 42, and 43). The power supply apparatus is configured to operate simultaneously the first power device (30) and the plurality of the second power devices (41, 42, and 43) to supply a DC power therefrom to a load device (92). The first power device (30) has its output voltage of a DC voltage kept constant irrespective of a magnitude of an output current of the first power device (30). The second power devices (41, 42 and 43) have its output voltage of a DC voltage which decreases monotonically as an output current of the second power devices (41, 42, and 43) increases, respectively. The second power devices (41, 42, and 43) include an adjustment unit configure to adjust the output current in accordance with an instruction value for prescribing a magnitude of the output current. The adjustment unit is configured to, upon receiving the instruction value, modify the output current-output voltage characteristics of the second power device under a condition where the output voltage of the second power device decreases monotonically as the output current of the second power device increases, thereby adjusting the output current of the second power device to a current corresponding to the received instruction value as well as adjusting the output voltage of the second power device corresponding to the adjusted output current of the second power device to the output voltage of the second power device corresponding to the unadjusted output current of the second power device.
