5.1 Connection adapter to flange part
Since the tolerances of the adapter to be connected to the flange portion depend on the
manufacturing process and are made with the dimensions specific to the customer and tolerances
cannot be recommended. However, for reference, the size of the flange adapter kid of the optional
component for evaluation of Fuji Electric is shown in Figure 5.
5.2 Selection of O-ring
When this IGBT is installed to a power control system, certain suitable O-ring is needed.
Size and material of O-ring depend on the system design and the operational environment of the
system. Therefore, when O-ring is selected, sufficient confirmation about seal performance shall be
needed.
There is an example of O-ring in Table 1 as the flange adapter kit for IGBT module evaluation.
Seal area of the flange for the flange adapter kit is shown in Figure 4.
5.3 Temperature check
After selecting a O-ring and determining the mounting position of the IGBT module, the temperature
of each part should be measured to make sure that the junction temperature (
T
v
j
) of the IGBT module
does not exceed the rating or the designed value.
