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...
• It should not saturate at the peak test currents.• It should limit the di/dt so that the switching times (T1, T2 and T3 in figure below) are not less than 10 μs, to ensure the devices have fully turned on or off.• The di/dt should not be so low that the switching ...
I have only made a basic double pulse test simulation circuit just to check the working condition of the spice model.So far I cant see any output from the simulation.I am using the 1st half bridge of the whole module in the simulation....
