Systems and methods for voltage regulation of high voltage direct current systems are provided. In certain embodiments, a system includes a generator that generates alternating current (AC) voltage. The system further includes a power converter that converts the AC voltage into regulated direct current (DC) voltage. Also, the system includes a voltage regulator. In additional embodiments, the voltage regulator includes an AC voltage regulator that regulates the AC voltage generated by the generator. Also, the voltage regulator includes a DC voltage regulator that regulates the DC voltage produced by the power converter. Moreover, the voltage regulator includes a regulator selector that selectively activates one of the AC voltage regulator and the DC voltage regulator based on a current from the power converter and at least one of a voltage of the generator and a voltage of the power converter.

Voltage regulation of high voltage direct current systems

An apparatus and a method detect arc faults in an electrical power distribution system of a vehicle. In one implementation, the apparatus () includes: a load current input () arranged to obtain a measurement of current being supplied to a load () via a solid state power switching device () of the electrical power distribution system; and an arc fault detector () arranged to compare the measured load current with a load signature, the load signature being a function of characteristics of the load () being supplied current via the solid state power switching device () and operating conditions of the solid state power switching device (). The arc fault detector () outputs an arc fault indication signal when the measured current is outside an allowable range of the load signature to provide protection against arc faults.
