<p><P>PROBLEM TO BE SOLVED: To provide an uninterruptible power supply having a short recovery charge time. <P>SOLUTION: In the uninterruptible power supply, a battery 6 is charged while supplying the electric power supplied to input terminals A, B to output terminals C, D, and the power is supplied to the output terminals from the battery when the power supply to the input terminal is cut off. As a battery charge maximum power value control means for controlling the battery charge maximum power value, the power supply is equipped with a current detection device 4 for detecting input current, a current detection device 5 for detecting battery charge current, and an A/D converter 1009, CPU 1010 and D/A converter 1011 to generate voltage level Icset for setting maximal charge power on receipt of current value information Ii and Ic from the current detection devices to set the charge current maximum value. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
