Abstract

See full text

A drive system includes a current sensor configured to generate a first current signal representative of a current flowing in one or more electrical devices electrically coupled together through a power supply bus, a power output bus, and a common ground. The drive system also includes a voltage sensor configured to generate a first voltage signal representative of a voltage with respect to the common ground in the one or more electrical devices. The drive system further includes a ground fault detection controller configured to determine a ground fault in the one or more electrical devices based on a change in at least one of the first current signal and the first voltage signal.
