GaN Systems™, an Infineon Technologies Company, today announced the winners for the 9th “GaN Systems Cup” Power Electronics Application Design Competition at the 2023 China Power Electronics and Energy Conversion Congress and the 26th China Power Supply Society Annual Conference & Exhibition (CPEEC & CPSSC 2023), taking place on November 10-13, 2023, in Guangzhou, China. The Southwest Jiaotong University team’s three-phase inverter prototype design was recognized as the Grand Prize for achieving outstanding efficiency and power density with GaN Systems’ high-performance power transistors.
Since 2015, the Power Electronics Application Design Competition has encouraged over a thousand college students to sharpen their knowledge with practical design experience and explore possibilities in power electronics.
Participation was again unprecedented this year, with 68 teams from 48 top universities submitting project proposals. Out of the 24 teams that entered finals, 10 eventually received recognition. The Southwest Jiaotong University team earned the Grand Prizes for their outstanding high-efficiency, high-power density three-phase inverter design. With an output power of 500W, an input voltage of 350VDC, and an output voltage of 220VAC with frequency increased from 50Hz to 400Hz and eventually 2000Hz, the team’s design delivered an impressive 15W/in3 power density and average 98% efficiency.
In addition to the Grand Prize winner, two teams from Huazhong University of Science and Technology and China University of Mining and Technology won the First Prize, three teams from Hangzhou Dianzi University, Hefei University of Technology, and China University of Mining and Technology won the Second Prize, and four teams from Tungnan University and Naval University of Engineering, Heilongjiang University of Science and Technology, Wuhan University, and South China University of Technology won the Third Prize.
“The power industry is constantly looking for novel approaches to create more powerful, smaller, and faster components that increase overall system power density and efficiency,” said Yunsheng Qu, Senior Manager of Infineon’s Power and Senor Systems Division, at the award ceremony. “GaN adoption is now at the tipping point in many applications, and developing a pipeline of skilled, talented engineers has become ever-crucial to support such massive market growth potential. I am pleased to see many of the winning entries not only meet the design requirements but go well beyond them.”
Co-located with the GaN Systems Cup, CPEEC & CPSSC 2023 drew a record-breaking 2,600 visitors and nearly 100 exhibitors, making it China’s largest academic event in power electronics. Infineon’s GaN Systems business line showcased an array of groundbreaking power system reference designs for automotive, industrial, and consumer applications. The impressively compact and economical 11kW 800V GaN-based onboard charger reference design was the main attraction in the booth. Visitors also showed a high level of interest in the implementation benefits enabled by the new Gen4 platform and responded positively to the closing of the Infineon acquisition.
CPEEC and CPSSC will resume on November 8-11, 2024 in Xi’an, China. We look forward to seeing you again.
