Abstract:
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.

Claim (Index 1):
A drive system comprising:\n 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; a voltage sensor configured to generate a first voltage signal representative of an AC input voltage including a common-mode component in the one or more electrical devices; extracting the common-mode component from the first voltage signal, the common-mode component representing a voltage drop across a common-mode choke due to ground fault currents when a ground fault is present, and a controller configured to determine the 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.
