GaN Systems sponsoring sixth annual China Power Supply Society ‘GaN Systems Cup’ design competition
GaN Systems Inc of Ottawa, Ontario, Canada (a fabless developer of gallium nitride-based power switching semiconductors for power conversion and control applications) is sponsoring the China Power Supply Society (CPSS) design competition, which focuses on innovation in energy conservation, emission reduction, and new energy utilization. Now in its sixth year, the GaN Systems Cup competition challenges engineering teams from China’s universities to design new or improved power electronics systems using GaN power transistors.
“Innovation continues to take place in power electronics and flourishes with competitions like the GaN Systems Cup that challenge young engineers to create solutions from design to build that address growing global power consumption and delivery needs,” says GaN Systems’ CEO Jim Witham. “GaN is part of that transformation in solving critical power systems challenges.”
This year, teams are tasked to design a high-efficiency and high-power-density bidirectional AC/DC converter with a 400W-rated output power, 220VAC input voltage and 300-400VDC output voltage while achieving 94% efficiency in both directions at full load, and no greater than 30W/cm3 power density. Additional factors such as total cost is evaluated as part of overall performance. Participating teams will be using GaN Systems 650V GS66502B transistor.
The competition is now underway, with submissions coming from universities all over China. In the coming months, the next stages will proceed, including the selection of teams entering the preliminary round at the end of June, the list of finalists to be announced in September, and a live finals and awards ceremony near the end of 2020.
The contest is organized in partnership with CPSS, the China Power Society Science Popularization Committee, and Huazhong University of Science and Technology, with participation from Ningbo Xici Electronic Technology Co Ltd and Itech Electronics Co Ltd.
