High Voltage Switching Test System
The advanced development of new technologies, such as SiC and GaN, have opened the opportunity for more efficient and higher voltage/power performance in switching and power management circuits. Their high cutoff frequencies, low on-state resistance, and very high breakdown voltages can increase power supply power handling densities approaching hundreds of watts/inch. Reliability of these new technologies and techniques is critical for realizing practical applications. While Silicon devices have a rich history of proven reliability, these newer compound semiconductor technologies are too new to have a reliability history and have not been well proven. Further, process variations, even in well-controlled lines, yield widely varying results. This has driven the need for additional testing and to burn-in devices prior to delivery.
