Abstract:
A modular power management system having common wiring for allowing both AC and DC power therethrough, said system capable of avoiding undesirable DC current paths as may be encountered due to a multitude of established neutral-line connections to earthing grounds established throughout in an AC power supply network, said system comprising:an electrical distribution panel, capable of receiving both AC and DC power simultaneously;a system of busses housed within the panel and including an electrical power buss, a neutral buss and a ground buss;a module unit including a source of DC power connected across said neutral buss and said ground buss within said panel;a connection for delivering AC power to said power, neutral and ground busses within said panel;an electric outlet having at least one connection element, connected to said AC power buss, a second connection element connected to said neutral buss, and a third connection element connected to said ground buss;a connector for selectively withdrawing AC or DC power for an external load constructed to engage with said electrical outlet so as to connect said load to selected connection elements within said electric outlet;a current responsive circuit interrupter protecting said external load, including at least one circuit interrupter ganged for simultaneous tripping of both AC and DC power to said connection elements connected to said neutral and AC power busses; anda DC isolation capacitor being connected, so as to provide DC blocking, with at least one common current path sharing AC and DC, said isolation capacitor having a sufficient capacitance to allow low loss passage of AC power.
