‘GaN Systems Cup’ China Power Supply Society Design Competition

0

GaN Systems is proudly sponsoring the distinguished 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 top engineering teams from China’s leading 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,” said Jim Witham, CEO of GaN Systems. “GaN is part of that transformation in solving critical power systems challenges, and we look forward to seeing the designs that the teams develop.”

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 in 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 which will be announced in September, and culminating in 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 in participation with Ningbo Xici Electronic Technology, and Itech Electronics.
