Abstract: A system for testing a ground fault detection system in an electric circuit establishes a ground connection between a bus and the ground via an inverter and a load by closing an inverter switch of the inverter and a grounding switch disposed between the load and the ground, determines whether the ground connection is detected, and determines a fault in the ground fault detection system responsive to the first ground connection not being detected by the ground fault detection system. Optionally, a ground fault may be identified by determining three phase voltages provided from each of plural inverters, determining symmetrical components of the three phase voltages for each of the inverters, and identifying a ground fault in one or more of the inverters while powered by the power supply based on the symmetrical components.

Abstract: A system for controlling multiple inverter-driven loads includes a controller that is configured to be coupled with an inverter that receives direct current and converts the direct current into an alternating current in order to supply the alternating current to plural loads that are connected to the inverter by plural respective contactors. The controller also is configured to control operations of the inverter and of the contactors in order to individually control which of the loads remain connected to and powered by the inverter and which of the loads are disconnected from the inverter.

Abstract: A control method comprises determining wheel creep of a wheel operably coupled to a traction motor and limiting a rate of change of an excitation frequency applied to the traction motor to drive the wheel, based on the determined wheel creep. According to one aspect, the rate of change of the excitation frequency is limited if the wheel creep exceeds a wheel creep threshold.
