  • Patent number: 10493930
    Abstract: A solid state primary power switching network for modular equipment centers (MECs) distributing primary power throughout a vehicle. The solid state primary power switching network includes multiple primary power switch network devices (PPSNDs) of a MEC for controlling and distributing primary power to other MECs spatially distribute throughout a vehicle. In one or more configurations, the PPSNDs have a universal structure in that each includes a common power input source and a plurality of common power outputs. In one or more configurations, primary power sources to the vehicle are switched without a perceivably visible break in power.

One example is a power conversion system for an electrical power system in a twin engine aircraft having a first generator and a second generator is described. The power conversion system includes a first branch, a second branch, and a selector. The first branch has a first input, a first power converter, and a first output configured for coupling to an aircraft electrical distribution system. The second branch includes a second input, a second power converter, and a second output configured for coupling to the aircraft electrical distribution system. The selector is coupled between the first branch and the second branch. The selector is configured to selectively connect the first generator to the first branch or to the first and second branches. The selector is also configured to selectively connect the second generator to the second branch or the first and second branches.

  • Patent number: 10050548
    Abstract: A method and apparatus for transferring power to a load. An AC-to-DC converter output for an AC-to-DC converter is connected to a filter circuit input in a DC-to-DC converter via a connector such that a no-break power transfer occurs when transferring between providing power for the load by the AC-to-DC converter and providing power for the load by the DC-to-DC converter. The topology of the AC-to-DC converter needs only 21 windings for achieving a 24-pulse transformer rectifier unit.

  • Patent number: 9561761
    Abstract: A plurality of modular equipment centers (MECs) spatially distributed throughout a vehicle servicing equipment loads. Each MEC independently provides localized power and communication to service the equipment loads. A zone of electrical loads is assigned to and serviced by the nearest MEC. Power and communication data are synchronized in that each equipment load receives power and data from the same MEC. In one embodiment, if a MEC experiences an operational inconsistency, one or more other MECs are assigned the equipment loads of the operationally inconsistent MEC.

  • Patent number: 9413162
    Abstract: Distributed electronic protections and control architecture enabling simultaneous fault clearance without conflicting fault isolation logic. A plurality of modular equipment centers (MECs) is spatially distributed throughout a vehicle to service equipment loads with power and data. In one embodiment, protective functions are embedded on integrated protection chipsets (IPCs) within the distributed architecture of the vehicle. The IPCs implement a plurality of protective functions where coordinated or independent fault assessments are performed.

  • Patent number: 9407083
    Abstract: A system and method for suppressing a subtransient current and an overvoltage in a power system. A subtransient current is identified at a location in the power system. The subtransient current at the location in the power system is directed to ground for a time delay in response to identifying the subtransient current at the location in the power system. Directing the subtransient current at the location in the power system to ground is ceased in response to identifying an end of the time delay. An overvoltage is identified at the location in the power system. The overvoltage at the location in the power system is suppressed in response to identifying the overvoltage at the location in the power system.
