Abstract:
In order to supply direct current to a plurality of consumer electronic modules (2 to 4), from an interfered direct voltage, with a wide range of voltage regulation, the power supply device comprises a primary supply module (5) including means for pre-adjusting voltage, for raising or lowering the direct voltage, to supply the modules (2 to 4) with a pre-adjusted voltage with a low range of voltage regulation, and in each module, converting means (6) supplying voltages adapted to the needs of the module.
Abstract:
An electrical distribution system and method has storage battery mechanism (M) of very large equivalent capacitance providing excellent ripple filtering and an ideal path to ground, a filter capacitor mechanism (FC) of microfarad size providing DC blocking and limited AC path to ground. The storage battery entity (SB) is maintained as to its charge by DC supply which provides regulated DC power in which switching regulation may be involved. The system and method provides dual voltage capability, both DC and AC in which circuit breakers (10, 12, 14 and 15) may be ganged for simultaneous tripping, and in which intrinsic DC circuit(s) (DBD) may be looped to increase current-carrying capability.
