Silicon carbide power devices, representing thirdgeneration semiconductors, are widely used in the areas of industrial control, rail transportation, electric vehicles, and renewable energy. As crucial components of power electronic systems, their reliability is vital to the safe operation of entire systems. Temperature is a critical factor affecting device reliability, and junction temperature serves as a key indicator reflecting the thermal state of the device. Accurate monitoring of junction temperature is therefore essential for tracking device conditions and assessing reliability. This paper provides a comparative review of advances in junction temperature monitoring for silicon carbide-based power devices, systematically analyzing four primary methods: thermal network model, temperature-sensitive electrical parameter, physical contact sensing, and non-contact optical methods.
