摘要：
This paper presents a SiC device junction temperature monitoring method. The device internal gate resistance has a consistent temperature dependence. With different junction temperature conditions, the equivalent gate loop impedance will be different and change the gate driver currents. Through proper signal processing, this gate loop current peak value can be captured and utilized as the junction temperature indicator. The concept and feasibility was verified through both simulation and experimental results.
