1. An electrical power distribution system, comprising:
- an AC to DC converter for providing low voltage DC power;
at least one USB port electrically coupled to said AC to DC converter by a voltage regulator, wherein said USB port is configured to provide a DC voltage line connection but not a data line connection; and
a switch coupled between said AC to DC converter and said USB port to selectively energize said USB port when a plug is inserted;
wherein said switch is configured to turn the AC to DC converter on when a plug is inserted into said USB port, and turn the AC to DC converter off when no plug is inserted into said USB port.

Abstract
An electrical power distribution system has fixed stations with AC power to DC power conversion circuitry at these stations. The converter(s) are switchable ON/OFF at outlet ports or sockets where the socket configuration permits. Standardized DC sockets accommodate a variety of voltage requirements typical of portable digital devices. In some embodiments feedback circuitry is provided to regulate the power to these devices in accordance with parameters programmed in the portable devices or in the sensing circuitry provided at each station.
