<P>PROBLEM TO BE SOLVED: To provide a DC power supply system capable of controlling the current or power of a storage battery at a prescribed value even when the storage battery is directly connected to a DC power supply section. <P>SOLUTION: A storage battery is directly connected to a DC power supply section where a distributed power source device, a load, and a system power arrangement are connected. The storage battery is provided with a storage battery current detector for detecting the input/output current thereof. The system power arrangement is provided with power converters for converting a DC to an AC, and an AC to a DC between the system power and the DC power supply section. According to storage battery current information obtained from the storage battery current detector, the power converters control their output so as to control the current or power of the storage battery at a prescribed value. <P>COPYRIGHT: (C)2012,JPO&INPIT |
