Zusammenfassung:PROBLEM TO BE SOLVED: To stabilize a voltage level of DC power supplied to a DC apparatus. SOLUTION: A voltage feedback part 21 of the DC apparatus 2 compares a voltage V3 changing in proportion to an applied voltage V2' of a DC supply line Wdc with a predetermined threshold value Vth and transmits the comparison result (information) to a DC power supply unit 1 through a feedback line Lf. In the DC power supply unit 1, a controller 11 controls a DC-DC converter 10 in accordance with information received from the DC apparatus 2 to adjust a voltage level V2 of the DC power supplied to the DC apparatus 2. Thus, the voltage level V2' of the DC power supplied to the DC apparatus 2 can be stabilized. COPYRIGHT: (C)2009,JPO&INPIT
