Perform Gate Driver Board
Resistance Measurements
To measure the gate driver board resistance, follow these steps.
1. Remove power from the AFE.
Remove Power from the AFE on page 37
.
2. If present, remove the protective barriers.
Remove AFE Protective Barriers on page 44
.
3. Remove the protective front covers and terminal covers from the power
structure for each phase (U, V, and W).
See
Remove Protective Covers from the Power Structure on page 47
.
There are three gate driver boards on the power structure, one for each
phase (U, V, and W).
4. Measure the power transistor gate interface resistance for each phase (U,
V, and W):
• The resistance from each ignition pin to the branch emitter pin
(connectors X10 and X11) is approximately 166 Ω.
• The resistance from the X10 branch emitter pin to the same branch
power terminal (U/T1, V/T2, and W/T3) is approximately 0.5 Ω.
• The resistance from the X11 branch emitter to the same branch
DC-bus terminal is approximately 0.5 Ω.
If any of the gate interfaces fails this test, replace the appropriate (left,
middle, or right) power module. See
the U, V, or W Phase Assembly on page 62

: Connectors X7 and X8 are connected in parallel

not have to be tested.
