OTTAWA, Ontario, November 5, 2019GaN Systems, the global leader in GaN power semiconductors, alongside the China Power Supply Society (CPSS), China Power Society Science Popularization Committee, and Tsinghua University, today announced the winners of the fifth annual “GaN Systems Cup” design competition at an awards ceremony at the China Power Supply Society Conference (CPSSC) on Nov. 3, 2019.

Paul Wiener, VP Strategic Marketing at GaN Systems, addresses CPSSC at the award ceremony for the Cup Challenge.

The annual contest challenges top engineering teams from China’s leading universities to design new or improved power electronics systems using GaN power transistors from design to build that meets specified requirements. This year’s challenge was to develop a high-efficiency, high power density AC/DC power supply for data center server power applications with GaN Systems’ 650 V power transistors. The design had to meet several requirements: 400 W rated output power, 220 VAC input voltage range/48 DC output voltage, and achieve 94% efficiency at 50% load and greater than 3W/cm3 power density.

Forty teams participated in the first round of the competition, 30 teams moved on to the second round, and 12 participated in the final competition. Five engineering teams were awarded for their GaN-based inverter designs. Cash awards of 20,000-yuan, 10,000 yuan, and 5,000 yuan were given to the top, first, and second winning teams:

Top Winner:

The top winners of the GaN Systems Cup from Zhejiang University.

  • Zhejiang University

First:

  • Huazhong University of Science and Technology
  • North China University of Technology

Second:

  • Nanjing University of Aeronautics and Astronautics
  • Heilongjiang University of Science and Technology

Honorable mentions go to:

  • Chongqing University of Technology
