4.2 Characteristics measurement
4.2.1 IGBT characteristics measurement
This section shows examples of measurement for the saturation voltage V
CES
between
collector/emitter of IGBT and the forward voltage (V
FM
) Peak Forward Voltage Drop in HIGH
CURRENT (large current) mode.
The diagram on the right in this frame shows
the measurement result of the saturation
voltage between collector/emitter V
CES
of an
IGBT based on the extracts from the IGBT
performance table below.
In addition, extracts from the performance
table of device characteristics which should
be investigated in advance is shown.
For connection method, see the connection
diagram on the next page.

Caution!
When starting or finishing measurement, operate CS-3000 as shown below:
When starting measurement, set HIGH VOLTAGE breaker to DISABLED and open the test fixture.
After connecting a measured device, set HIGH VOLTAGE breaker to ENABLED.
After finishing measurement, rotate VARIABLE counterclockwise to set the value to 0% (to discharge
applied voltage).
Set HIGH VOLTAGE breaker to DISABLED.
