摘要： A system comprising a controllable alternating current power source; an active rectifier coupled to the controllable alternating current power source and configured to rectify an output of the controllable alternating current power source to supply a direct current to a load; and a controller configured to adjust at least one of a parameter of the controllable alternating current power source and a parameter of the active rectifier in response to a target output.

摘要： Systems and methods of providing fault protection on direct current (DC) feeds to various engine or generator set components are provided. In some embodiments, generator set includes a ground fault device arranged between a DC power distribution circuit and a subsystem of the generator set. The ground fault device is configured to detect a fault condition based on a comparison of a first current in a first wire with a second current in a second wire between the DC power distribution circuit and the subsystem. In response to detecting the fault condition, the ground fault device is configured to disconnect the subsystem.
