    摘要： A rear-loaded electronics array, comprising a first circuit board assembly comprising a rail and at least one slat assembly. The at least one slat assembly can be operable to be removed from the rail and replaced on the rail from a rearward position. A second circuit board assembly can comprise a rail and at least one slat assembly. The at least one slat assembly can be operable to be removed from the rail and replaced on the rail from a rearward position. The first circuit board assembly can be positioned adjacent the second circuit board assembly, and the first circuit board assembly can be coupled to the second circuit board assembly, thus forming the rear-loaded electronics array. The first and second circuit board assemblies can be installed and removed independent of one another, as well as each of the individual slat assemblies from any circuit board assembly.

    摘要： A power converter with ground fault protection (PCGFP) circuit includes an input stage, a first voltage converter, and an output stage. The input stage is connected to a power bus to receive an input direct current (DC) voltage. The first voltage converter converts the input DC voltage to a second voltage and switches between an open and closed state to regulate power present on the power bus. The output stage includes a second voltage converter circuit to generate an output voltage having a different voltage level from the input DC voltage. A controller controls operation of the first and second voltage converters and is also capable of detecting a ground fault on the power bus. The controller operates the first and second voltage converts in a fault isolation mode in response to detecting the ground fault such that the first and second voltage converters isolate the ground fault.

    摘要： A modular high-power converter system includes an electronic power distribution unit configured to output an analog current (AC) voltage to a power bus, and at least one Transmit or Receive Integrated Microwave Module (T/RIMM) that includes a voltage converter unit and a transmitter and receiver (T/R) unit. The voltage converter unit includes at least one analog-to-digital converter (ADC) to convert the AC voltage into a direct current (DC) voltage having a first DC voltage level. The transmitter and receiver (T/R) unit includes a modular-based DC/DC converter to convert the DC voltage into a second DC voltage having a second voltage. The modular-based DC/DC converter includes a modular power converter unit configured to generate the second DC voltage. The modular converter unit is configured to be independently interchangeable with a different modular converter unit.
