Abstract

An electrical distribution system and method has storage battery mechanism of very large equivalent capacitance providing excellent ripple filtering and an ideal path to ground, and filter capacitor mechanism of microfarad size providing DC blocking and limited AC path to ground. The storage battery entity 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 may be ganged for simultaneous tripping, and in which intrinsic DC circuit(s) may be looped to increase current-carrying capability. A DC isolation capacitor is connected to a common current path, such as to one of the busses, such as, for example, in series with the neutral circuit, as a means for avoiding undesirable DC current paths as may be encountered due to a multitude of established neutral-line connections to earthing grounds established throughout in AC power supply network. This isolation capacitor is of sufficient capacitance to allow the low loss passage of unbalanced AC if the loads connected to the distribution system produce unequal currents in the common wiring.
