Test setup

Figure 16 captures the test setup and voltage measurement techniques for double-pulse testing. The first turn-
on pulse of the low-side device (S2) establishes the desired current value (e.g. nominal data sheet current in
this case) in the inductive load, and the turn-off pulse makes the current flow in the freewheeling diode (e.g.
body diode of the top device S1 in this case). An external inductance value was used in the actual test setup.
The second turn-on pulse measures the low-side device turn-on characteristics, which also include the reverse
recovery of the freewheeling body diode.
