Abstract: A system includes a generator. Three AC feeders are connected for feeding AC output from the generator. A rectifier is electrically connected to the three AC feeders and to a load via a first DC feeder and a second DC feeder. A first resistor connects between a the first DC feeder and ground. A second resistor connects between the second DC feeder and ground. At least one of a first current sensor is operatively connected to detect current in the first DC feeder and/or a second current sensor is operatively connected to detect current in the second DC feeder. A controller is configured to monitor for changes in common mode current based on the input from the at least one current sensor, and to determine presence of a fault if change in the common mode current exceeds a predetermined threshold.

Abstract: An aircraft engine thermal management system includes a body having a coolant passage in thermal communication with an electronic device, wherein the body and the electronic device are located in a first portion of the aircraft. A generator is fluidically connected by a coolant path to the coolant passage wherein the generator is located in a second portion of the aircraft, with at least a portion of the coolant path is located within a cooling location having a lower average temperature than either the first portion or the second portion of the aircraft.

Abstract: A high voltage DC (HVDC) system can include a generator configured to output alternating current (AC), a rectifier connected to the generator via AC phase lines, the rectifier configured to convert the AC to DC to output the DC to DC feeder lines, and a crowbar system. The crowbar system can include a switch module operatively connected to the AC phase lines to prevent AC from flowing to the rectifier in a cutoff state. The crowbar system can be configured to determine whether at least one cutoff condition exists. The at least one cutoff condition can be or include one or more of a DC overcurrent downstream of the rectifier, a DC overvoltage downstream of the rectifier, an AC overcurrent from the generator, or an arc fault. The crowbar system can be configured to control the switch module to the cutoff state if the at least one cutoff condition exists.

Abstract: A system includes a generator. Three AC feeders are connected for feeding AC output from the generator. A rectifier is electrically connected to the three AC feeders and to a load via a first DC feeder and a second DC feeder. A first resistor connects between a first one of the DC feeders and ground. A first voltage sensor is operatively connected to detect voltage across the first resistor. A second resistor connects between the second DC feeder and ground. A second voltage sensor is operatively connected to detect voltage across the second resistor. A controller is configured to monitor for changes in common mode voltage based on the input from the first sensor and from the second sensor, and to determine presence of a fault if change in the common mode voltage exceeds a predetermined threshold.

Abstract: A power supply system to provide power to a load connected between first and second connectors. The system includes a generator that produces an alternating current generator output and a rectifier that 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. The system also includes a filter connected to the rectifier and between the connectors and that smooths the DC output. The filter includes a midpoint configured to be connected to ground. The system also includes a fault clearing source connected to the first connector that provides a clearing voltage to the first connector when a ground fault occurs on the first connector.
