Abstract
A broadband system that simultaneously delivers output power and supplies a broadband signal and has a redundant bus power supply. The system includes a central office having a video gateway. The system further includes a plurality of nodes having a power supply and a combiner for coupling the broadband signal to the power supply output. At each node, a distribution line delivers broadcast services and power to a consumer site. The power supply comprises a battery source, rectifier, filter, inverter and generator to provide a secondary DC power source. The various elements of the power supply are diode isolated and are interconnected via a redundant power bus, thus allowing power to be maintained to the subscribers even in case of failure of one or more elements of the power supply. The power supply further includes a plurality of inverters, each inverter supplies power to a distribution line. A controller monitors the status of each inverter and secondary power source. In addition, the controller monitors output power supplied by each inverter. The controller exchanges control and status information with the power supply and secondary power source through a memory array. By issuin…
