ECE 599 ― Characterization of WBG Devices
This is a hands-on, lab-based course introducing techniques and best practices for the characterization, driving, and protection of WBG devices. Students perform experimental static and dynamic testing of WBG devices, and develop models of experimental performance. Characterization results enable advanced modeling, design, and optimization of power converters leveraging wide bandgap devices.
Instructor Resources are available which give a complete course schedule, homework assignments, lecture notes, PCB design files, and lab equipment inventory for the course.Instructor Resources
The course was first taught in Fall 2017. The enrollment was 16 students, who worked in eight groups of two. Throughout the course, groups characterized and modeled four WBG transistors (2 SiC, 2 GaN).
Course content incudes
- • Performing static characterization using a Keysight B1505A high power curve tracer
- • Modeling/Simulating switching behavior of the devices
- • Designing, constructing, and debugging a double-pulse-test circuit board for dynamic characterization
