WebApr 23, 2024 · Abstract: The withstand capability and threshold voltage (VTH) instability of 1.2-kV silicon carbide (SiC) MOSFETs under repetitive short circuit (SC) tests are investigated. An SC test system is constructed to apply repetitive SC stress to SiC MOSFETs and measure the transfer I-V characteristics and gate-to-source leakage …
WebMar 23, 2016 · Dynamic effects fall broadly into radial and axial forces/stresses. Radial forces/stresses can usually be calculated quite easily by 'pencil and paper' but axial forces and the resulting stresses require a detail knowledge of the magnetic field within the windings. ...

When the clamping force exerted on the winding decreases, the strength of the buckling decreases relatively as a result of a decrease in the axial clamping force during a short circuit. Buckling occurred when the initial clamping force was 100% and the residual clamping force was decreased below approximately 30%.
WebJun 30, 2000 · The static test is used to define the device operating conditions and the dynamic short circuit test is used to characterize the limiter`s performance. With the superconducting limiter in the test circuit, short circuit fault currents are limited to a few times the nominal current.
