Winners from the annual China Power Supply Society (CPSS) competition were honored at the organization’s annual meeting on 22 November by sponsor GaN Systems Inc of Ottawa, Ontario, Canada (a fabless developer of gallium nitride-based power switching semiconductors for power conversion and control applications) alongside CPSS, China Power Society Science Popularization Committee, and Nanjing University of Aeronautics and Astronautics. This year’s theme focused on the application of power electronics technology for innovation, energy savings, and new energy use.
Thirty-one teams participated from 29 universities throughout China. The teams were challenged to create a single-phase DC-AC inverter with 400V DC input, 500VA output power, and 95% minimum efficiency, in a small form factor. The final 10 teams competed at the CPSS meeting. Entries were evaluated based on performance criteria, including inverter efficiency, power density, and output stability across various load conditions. Cash awards of 20,000-yuan, 10,000 yuan, and 5000 yuan were given to Top grade prize, Number 1 prize, and Number 2 prize finishers.
Six power design engineering teams were awarded for their high-efficiency, high-power-density GaN-based inverter designs. The Top Grade Prize was given to NUAA (Nanjing University of Aeronautics and Astronautics), Number 1 Prize to Xi’an Jiaotong University and Shanghai University of Electric Power, and Number 2 Prize to Chongqing University of Technology, Heilongjiang Institute of Science and Technology, and Zhejiang University. The team from NUAA demonstrated good operating performance, high level power density and thermal performance, and a compact and inexpensive system design.
“We’re continually inspired by these young engineers and their approach and use of GaN transistors to solve current and future power system challenges,” said GaN Systems’ Jim Witham. “Solutions developed from the award recipients demonstrate the advantages GaN transistors enable to make designs smaller and more efficient.”
GaN Systems has supported this annual competition for several years, helping to accelerate and proliferate the learning of system development with GaN transistors to address the applications needs of the most demanding industries, including data centers, renewable energy systems, automotive, industrial motors, and consumer electronics.
In addition, GaN Systems had an educational role at the China Power Supply Society Conference 2017, which drew more than 1000 researchers and scholars in power electronics. The firm presented a 3.5 hour technical seminar providing continuing education of GaN power transistors and applications, and an industrial paper, which provided an in-depth industry overview of the GaN technology market as well as GaN use cases in several industries.
