The thermal performance is evaluated at 310 V
IGBT: The maximum case temperature is 86 ℃. The junction temperature is less than 100 ℃ calculated by
The key component temperatures are all in the normal range:
•
Shunt resistor: The shunt resistor is rated 3 W @ 70 ℃ in the operating temperature range of -55~155 ℃.

The maximum shunt temperature is 63.8 ℃ with a large margin.
•
Gate driver IC: The maximum junction temperature of the 2ED2106S06F is 150 ℃. The case temperature is
50.1 ℃. The gate driver IC power loss consists of two major parts, the internal level-shift switching loss and
