Low-Complexity Sub-Nanosecond Digital Active Gate Driving for IV-Trajectory Control in SiC Modules
This paper presents a low-complexity digital active gate driver, utilizing only two gate resistances with a single resistance changeover per switching event as well as a novel clock-frequency tuning method for sub-nanosecond timing resolution.
In combination with a low-cost FPGA, an effective timing resolution of 400 ps is reached, a tenfold improvement over conventional delay-based timing. Insights in the design as well as electrical and IV-trajectory measurement results are presented. The approach enables further innovation due to significantly mitigating the trade-off between switching loss and voltage overshoot in applications such as SiC power modules, high-current converters, and other fast-switching power electronic systems. This paper showcases its capabilities on a 400 A, 1200 V SiC module switching 300 A at 800 V, achieving a 46% reduction in switching loss for the same voltage overshoot.
