6.3.2 Diode Turn-off (300V, 25A, 150°C)
The simplified circuit of the Diode turn-off testbench is shown in Figure 30. Please note that the
environmental conditions are different from a standard characterization testbench, where the maximum
module performance is characterized. The gate driver has in this setup +15V/0V supply and Rg,on=2.2Ω. No
booster stage is implemented. The gate driver achieves in this case ≈0.7A peak current.
Figure 30 Equivalent circuit of the Diode turn-off testbench. DUT is the low right Diode. The low side
shunt is bridged and the current If is measured with a Rogowski current probe. The waveforms are
measured during the second turn-on pulse.
