Low side driver output

3 Test results

3.1 Double pulse test

The double pulse test is used to evaluate the switching characteristics of a power switch under hard

switching but in a safe manner.

For a low side switch the setup is as shown below:

The low side switch is driven with two pulses as shown below. The high side switch can be held off or

driven with the inverse of the low side gate switch (with adequate dead time).
