GaN Systems Cup to be contested by 14 finalists
GaN Systems Inc of Ottawa, Ontario, Canada (a fabless developer of gallium nitride-based power switching semiconductors for power conversion and control applications) says that, of the 35 teams that entered the ‘GaN Systems Cup’ China Power Supply Society (CPSS) design competition in April, 14 teams have been selected to move on to the live final round.
Teams going to the final round and awards ceremony (to be held in December) include: Beijing Jiaotong University, Hangzhou University of Electronic Science and Technology, He Hai University, Heilongjiang University of Science and Technology, Huazhong University of Science and Technology, Kunming University of Science and Technology, Nanjing University of Science and Technology, Shanghai Maritime University, Shanghai Jiaotong University, Xi’an Jiaotong University, Yanshan University (Liu Meng Group), Zhejiang University, Chinese Academy of Sciences University and Chongqing University of Technology.
Now in its sixth year, the GaN Systems Cup is a student competition in power electronics and related majors in China. Each competition has brought together the top engineering teams from leading universities to showcase what’s possible in new or improved power electronics systems using GaN power transistors.
This year, teams are challenged to design a high-efficiency, high-power-density bidirectional AC/DC converter using GaN Systems’ 650V GS66502B transistors that meet several requirements:
- 400W rated output power;
- 220VAC input voltage and 300–400VDC output voltage;
- achieve 94%+ efficiency in both directions at full load;
- >30W/cm3 power density; and
- additional cost and performance factors.
GaN technology has become a critical part of power systems across industries, from consumer electronics, data-center, industrial, automotive and renewable energy applications – areas that demand greater efficiency, power and performance.
The 2020 GaN Systems Cup is sponsored by GaN Systems, the CPSS and its Science Popularization Working Committee, Ningbo Xici Electronic Technology Co Ltd and Itech Electronics Co Ltd, and undertaken by Huazhong University of Science and Technology.
