摘要： A power system includes a traction battery, and a rectifier including a pair of diodes, a pair of switches, and a pair of capacitors each in parallel with a different one of the switches such that alternating current input to the rectifier results in alternating voltage having parabolic approaches to maximum magnitude values being input to the rectifier. The maximum magnitude values correspond to a magnitude of voltage output to the traction battery.

摘要： Systems devices and methods are disclosed for detecting DC arc faults in a high voltage vehicle electrical distribution system. An example vehicle includes a high voltage electronic system comprising a current sensor configured to capture current data and a processor. The processor is configured to generate filtered data by applying a filter to the current data, determine a Hurst exponent based on the filtered data, and responsive to determining a threshold change in the Hurst exponent, detect the presence of a DC arc in the high voltage electronic system.
