  • 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.
