A generator supplies power to the power distribution box, and a load receives power from the power distribution box. The power distribution box includes a board supporting plug-in pins receiving the power. A contactor is supported by the board to selectively providing power to a secondary power distribution connector supported on the board. The board includes power traces that are run within the board to connect the plug-in pins to the secondary power distribution connector. Protection and secondary power distribution circuitry is also supported by the board and connected to the contactors and/or power traces by control traces. The power and control traces eliminate loose wiring and harnesses. | 11-05-2009 |
20100002343 | GROUND FAULT INTERRUPTS FOR SOLID STATE POWER CONTROLLERS - A solid state power control scheme is provided with a ground fault interrupt function. Essentially, if a neutral wire is associated with the power supply, the current is sensed in that neutral wire. The sensed neutral wire current is subtracted from a summed current on the power supply lines. If that result is greater than a predetermined limit, then the ground fault function is actuated and the circuit is opened. For power supplies, both those with and without neutral wires, the current is sensed by a shunt resistor on the power supply line. | 01-07-2010 |
20100172062 | SOLID STATE POWER CONTROL MODULE WITH REMOVAL DETECTOR - A solid state power control module contains non-volatile memory. A switch for opening is provided to break a supply of power to a component. The switch is operable to trip (open) when an undesirable condition is detected, and further to be opened upon receiving a control signal. A status of the switch is stored in the non-volatile memory. A detector is provided for identifying when a module has been mounted in a housing, and communicates with the non-volatile memory if it is determined that the module is newly installed in a housing. A system and method are also claimed. | 07-08-2010 |
20110037315 | POWER DISTRIBUTION ARCHITECTURE FOR AIRCRAFT - An aircraft power distribution architecture includes a power rail extending generally along the length of an aircraft for receiving power from a generator, and for distributing power through plug-in modules located along the length of the power rail. | 02-17-2011 |
20120007424 | RING POWER DISTRIBUTION LOOP - A power loop is formed by a plurality of loop segments connectable by switches to form the power loop. The power loop is configured to receive power from a plurality of power sources. The switches connect the power loop to a plurality of components. A method is also disclosed and claimed. | 01-12-2012 |
20120007427 | NO BREAK POWER TRANSFER WITH SOLID STATE POWER CONTROLS - A method of controlling a power system provides at least two alternative sources of power delivering power to a power bus. Switches are provided between each of the at least two sources of power and the power bus. The bus is powered by a first of the at least two sources of power. A characteristic of the power supplied by the sources of power is monitored. Switching from the first source of power to a second source of power occurs by opening a switch associated with the first source of power, and closing the switch associated with the second source of power. The timing for performing the switching is selected such that one or more characteristics of the power supplied by the first and second sources of power are close to each other to minimize the apparent break in the power. A power system incorporate controls for effecting the method. | 01-12-2012 |
20130252473 | GANGABLE POWER SUPPLY CHANNELS - An interface module includes a first side having a plurality of input connectors of a same cross-sectional area corresponding to a same amperage rating, a second side having a plurality of output connectors of different cross-sectional areas from each other corresponding to different amperage ratings from each other, and wiring in the interface module configured to connect a first number of input connectors to a first one of the output connectors having a first amperage rating, and configured to connect a second number of input connectors to a second one of the output connectors having a second amperage rating different from the first amperage rating. | 09-26-2013 |
