PURPOSE:To apply a proper DC voltage from two systems of DC supply systems to one-system power receiving equipment with respect to the power supply system in an exchange having the two systems of DC supply systems. CONSTITUTION:One DC supply system 101 is generated by connecting diodes 300 of forward connection in parallel from DC supply systems 100. Power is supplied from the one DC supply system 101 to one-system power receiving equipment 200, and the one-system power receiving equipment 200 is provided with a DC voltage conversion means 201 correcting a voltage drop by the diode 300 produced in the DC voltage fed from the one-DC supply system 101 to the one-system of power receiving equipment 200 and applying the corrected voltage to the equipment 200. |
