SYSTEM, METHOD AND APPARATUS FOR PROVIDING DIRECT CURRENT

摘要

A system and method for providing direct-current power is described. In one embodiment a direct current voltage is converted into at least two regulated DC voltages, and a first of the at least two regulated DC voltages is applied across a first and second outputs and a second of the at least two regulated DC voltages is applied across the second output and a third output. And when a first impedance across the first and second outputs is less than a second impedance across the second and third outputs, current is received via the second output while delivering power to the first and second impedances.
