  • Patent number: 10899231
    Abstract: A vehicle includes an inverter configured to power an external device. The vehicle further includes a controller programmed to cause the inverter to output a voltage at a steady-state amplitude and a steady-state frequency and, responsive to detecting an inrush current event in progress that is caused by the external device, operate the inverter to reduce the voltage to prevent an overcurrent. The controller is programmed to identify the type of load connected and return the voltage to the steady-state amplitude and steady-state frequency based on the type of load.

  • Patent number: 10640003
    Abstract: The methods and systems for correcting for an inductive load when testing high voltages devices are described. A high voltages device is a device under test (DUT) in a double-pulse test, which may require the inductive load. The method can include in a low current, high voltage time period, estimating an inductor current contribution range after a turn on of the device-under-test connected to an inductive load with an air core inductor. The method subtracts the estimated inductor current contribution from a device-under-test collector current to output a corrected collector current. This allows the double pulse test to be conducted with an air-core inductor. Vehicles can use the DUT in traction power applications.
