Wide-bandgap (WBG) materials, such as GaN and SiC, offer high switching speeds, low losses, and withstand high temperatures and high voltages. Consequently, these materials are used in power products, fast chargers, electric vehicles and rail transit, as well as in 5G infrastructure and data center servers. However, these advantages increase the complexity of design and testing.
NCUOSC successfully used the Keysight PD1500A Dynamic Power Analyzer and Dual Pulse Tester (DPT) platform to establish a third-generation open WBG semiconductor laboratory to improve development and testing efficiency. While JEDEC, a global leader in developing open standards and publishing for the microelectronics industry, continues to define dynamic testing for WBG devices, standardized tests are beginning to emerge. The PD1500A DPT determines key performance parameters required by all standards, such as on/off and switching characteristics, dynamic conduction resistance, dynamic current and voltage, as well as reverse recovery, gate charge, and device output characteristics.
“Keysight is happy to work with NCUOSC to help engineering teams characterize, understand, integrate, deploy, and advance innovations for the next generation of semiconductor technologies,” said Thomas Goetzl, vice president and general manager of Keysight’s Energy and Automotive Solutions business unit.
Reliable and repeatable measurements are critical for accelerating the design and validation of new technologies, including wide-bandgap semiconductors. The intelligent features of the Keysight PD1500A , such as fully automated parameter extraction software based on IEC and JEDEC standards, loop testing, voltage and current sweep testing, and automated high-temperature testing, can help advance future innovations.
“The PD1500A DPT enables NCUOSC to reliably characterize WBG devices and effectively innovate in GaN and SiC applications. Its safety protections, scalability, and optional measurement tools provide the flexibility we need for future expansion,” said Professor Yue-Ming Hsin, Director of NCUOSC. “In addition to the PD1500A B1505A/N1265A Power Device Analyzer and Curve Tracer to achieve comprehensive and crucial characterizations of WBG semiconductors. We are pleased to collaborate with Keysight and contribute to the 5G/6G and electric vehicle ecosystem.”
