Patent number: 11088535Abstract: 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.Type: GrantFiled: April 12, 2019Date of Patent: August 10, 2021Assignee: RAYTHEON COMPANYInventors: Boris S. Jacobson, Steven D. Bernstein
