Abstract:
Gallium nitride (GaN) power devices promise better performance and efficiency compared to silicon (Si) transistors. However, due to the higher switching speed, parasitic elements have a larger impact on the switching transients and therefore characterization is more challenging. This paper presents a detailed comparison of the switching behavior of commercially available GaN and Si power devices rated at 100 V. A double pulse tester (DPT) with clamped inductive load was built for each device and layout design, hardware setup and measurement issues are proposed. Based on experimental data switching performance and losses are analyzed.
