  • Publication number: 20240322554
    Abstract: A power supply system is configured to provide power to a load connected between first and second connectors. The system includes a generator that produces an alternating current generator output. A rectifier receives the alternating current generator output and converts it into a direct current output and provides the direct current (DC) output between the first and second connectors. A filter is connected to the rectifier and between the connectors to smooth the DC output. The filter includes a midpoint configured to be connected to ground. A positive fault locating resistor is switchably connected to one of the first and second connectors by a switch configured to be normally open, and to switch closed upon detection of a ground fault so the positive ground fault locating resistor can provide a sustained level current for locating and clearing the ground fault.

  • Patent number: 12099096
    Abstract: A method includes performing a test for transformer rectifier unit (TRU) backfeed protection by removing AC power supplied to the TRU but keeping the TRU contactor closed for a first predetermined span of time. The method includes observing the TRU for a second predetermined span of time. The method includes determining if the contactor opens during the second span of time, that a TRU backfeed protection is functional and passes the test, and determining if the contactor does not open during the second span of time, that the TRU backfeed protection has failed the test.

  • Patent number: 12092236
    Abstract: A valving system has an actuator member connected to move with an actuator piston and change the position of a valve member. There is a smaller face fluid chamber acting on a small area piston face, and a larger face fluid chamber acting on a larger face of the actuator piston. The torque motor has an armature and a flapper caused to move by current received at the armature. The flapper moves between two fluid ports to control the pressure in the larger face chamber. The flapper further has a positioning extension engaging a first feedback spring operable between it and a forward face of the actuator piston and providing a spring force in combination with a spring force from the positioning extension. A control is operable to provide current to the armature to control the fluid received in the larger face chamber. The controller is programmed to associate the current supplied to the armature to an actual position of the valve member. A method is also disclosed.
