  • Voltage regulation of high voltage direct current systems
    Patent number: 11770084
    Abstract: Systems and methods for voltage regulation of high voltage direct current systems are provided. In certain embodiments, a system includes a generator that generates alternating current (AC) voltage. The system further includes a power converter that converts the AC voltage into regulated direct current (DC) voltage. Also, the system includes a voltage regulator. In additional embodiments, the voltage regulator includes an AC voltage regulator that regulates the AC voltage generated by the generator. Also, the voltage regulator includes a DC voltage regulator that regulates the DC voltage produced by the power converter. Moreover, the voltage regulator includes a regulator selector that selectively activates one of the AC voltage regulator and the DC voltage regulator based on a current from the power converter and at least one of a voltage of the generator and a voltage of the power converter.

  • Secondary electric power distribution system (SEPDS) to facilitate aircraft connectivity
    Patent number: 10998935
    Abstract: A secondary power distribution box (SPDB), solid state power controller (SSPC) line replacement module or printed board assembly (LRM/PBA), integrated power distribution and avionics system, and method of power distribution are disclosed. For example, the method includes receiving electrical power from a power source at a power feeder network, communicating with at least one load of a plurality of loads at least in part over the power feeder network, and coupling the electrical power to the at least one load of the plurality of loads in response to the communicating.
