Abstract
Apparatus and method is disclosed for overcoming the voltage attenuation and ground shifts normally associated with providing DC power to distributed loads from a DC power supply without the need for excessively large conductors, the need to distribute the DC power supply or the need to provide converters at or near each load. Reasonably accurate voltage regulation at each load is provided according to the invention while using low but not insignificant resistance power conductors by providing similarly low resistance voltage sense conductors. The loads are connected between the sense conductors in a distributed fashion. Current approximating that drawn by each load is injected from the power conductors to the sense conductors at or near each load. Dynamic current requirements are supplied by capacitors connected across each load, usually mounted on the load circuit boards. Stability during power up is provided by capacitors connected between each power conductor and it's respective sense conductor at the power supply.
