<P>PROBLEM TO BE SOLVED: To provide a power supply unit capable of regulating power obtained from a power supply module of a plurality of power supply units connected in parallel with each other. <P>SOLUTION: The respective power supply units U1 to Un of this power supply system 1 includes a voltage detection circuit 14 for detecting the voltage between both terminals of the power supply module 10, a current detection circuit 16 for detecting the current passing through the power supply module 10, a boosting/step-down circuit 13 for boosting the voltage between both terminals of the power supply module 10 and outputting the voltage to a pair of connection terminals, and a control circuit 17. The control circuit 17 calculates the electric power of the power supply module 10 on the basis of the detection result of the voltage detection circuit 14 and the detection result of the current detection circuit 16; outputs the calculated electric power result W to other connected control circuit; and prepares and outputs a control signal to the boosting/step-down circuit 13 on the basis of a target output voltage Vref of the boosting/step-down circuit 13, the calculated electric power result W, and a calculated electric power result Wref obtained from the other connected control circuit. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
