Abstract

Abstract A power distribution system delivers power onto a regulated bus to a load from a plurality of individual indivisible DC power source devices and or DC energy storage devices each having a respective regulator for coupling the devices onto the bus. Respective storage device chargers for the DC energy storage devices enable charging of the DC energy storage devices when the DC power source devices provide power in excess of the demands of the load. The respective regulators and chargers continue to provide sufficient coupled power onto the bus even in the event of a failure of one or more of the devices thereby enabling graceful degradation of power delivery to the load for improved reliably of the power delivery.
