4 FAQs about [Inverter power module maximum junction temperature]

Is junction temperature estimation a method of IGBT thermal management for inverters?

This paper presents a method of IGBT thermal management for inverters based on junction temperature estimation. In consideration of the constraints of junction temperature and power quality, the fluctuation in IGBT junction temperature is suppressed by changing switching frequency.

Does junction temperature fluctuation affect the operating lifetime of IGBT modules?

Junction temperature fluctuation is an important factor affecting the operating lifetime of IGBT modules. Many active thermal management methods for suppressing junction temperature fluctuation exist, but research on the implementation of thermal management in converters is limited.

Why do IGBT power inverters fail?

IGBT power modules’ high generated power losses convert to heat and raise temperature strains, particularly the junction temperature of the module. IGBT module failures are a critical worry for the dependability of power inverters since these temperature stressors have a substantial impact on the operation of such electronic components [4, 5, 6].

How to measure module junction temperature through an experimental setup?
