Example embodiments disclose a drive system including a machine including a plurality of phases and configured to generate power based on a plurality of phase currents, each respectively associated with the plurality of phases and a direct current (DC) bus, operatively connected to the machine. The DC bus includes a high-sideline, a low-side line and an inverter including a plurality of switching systems operatively connected between the high-side and the low-side lines the plurality of switching systems, each configured to output a respective one of the plurality of phase currents. The drive system also includes a controller operatively connected to the DC bus and the machine, the controller configured to determine if a failure exists in the drive system based on the plurality of phase currents and a DC bus voltage the DC bus voltage being a voltage across the high-side and low-side lines. |
