<P>PROBLEM TO BE SOLVED: To obtain a system linkage device that eliminates unnecessary operation when a system power supply returns to a normal state from an abnormal state, and feeds stable power to a load. <P>SOLUTION: In the system linkage device constituted such that the system power supply and the load are connected with each other via a switch, a second power supply is connected to the load side of the switch via a power converter, and the second power supply is linked to the system linkage power supply, when an output current command outputted from a current command generation circuit is switched to a system linkage current command for making a feeding system to the load serve as the system power supply at the normal time of the system power supply from a constant voltage control current command for setting an output voltage of the power converter to be a prescribed constant voltage, the change amount of the output current command is limited in a prescribed range, thus eliminating the unnecessary operation of the system linkage device. <P>COPYRIGHT: (C)2007,JPO&INPIT |
