Abstract
In some examples, an electrical power system includes a differential bus, a power converter coupled to the differential bus, and a controller configured to control the power converter based on a first target value for the differential bus. The controller is also configured to sense that a ground fault has occurred in the electrical power system while controlling the power converter based on the first target value. The controller is further configured to, responsive to sensing that the ground fault has occurred, control the power converter based on a second target value for the differential bus, the second target value being different than the first target value.
