摘要 |
<P>PROBLEM TO BE SOLVED: To decrease the rate of a harmonic component by increasing efficiency of AC/DC conversion of a DC power supply for operating a plurality of DC power supply units in parallel. <P>SOLUTION: A DC power supply comprises a plurality of DC power supply units which are equal in rated output to one another and which are connected together in parallel, and a control circuit which controls an output current value of a first DC power supply unit among the plurality of DC power supply units depending on an output request signal indicating a request value as a current value or a power value to be output and which individually brings a second DC power supply unit except the first DC power supply unit into a rated operation or stops the second DC power supply unit. <P>COPYRIGHT: (C)2012,JPO&INPIT |
