GaN Systems, the global leader in gallium nitride power semiconductors, announced that 16 teams from China’s top universities have been selected as finalists in the 8th annual “GaN Systems Cup” College Power Electronics Application Design Competition.
The competition, first launched by the China Power Supply Society (CPSS) in 2015 as an exploratory engineering practice activity for college students across the country - is the highest-level college student competition in the country’s power electronics field. Finalists have been selected based on their prototype design work around high-efficiency and high-power density single-stage photovoltaic inverters using GaN Systems’ power transistors.
This year’s competition, which kicked off in January 2022, appealed to a broad universe of college students- attracting 64 teams from 46 colleges and universities across the country. In May, project proposals of participating teams were reviewed, and 50 teams were selected to enter the preliminary competition.
The 16 finalists will present their designs concurrent with this year’s 25th Annual Academic Conference of China Power Supply Society (CPSSC 2022), co-located with the 2022 China Power Electronics and Energy Conversion Conference (CPEEC 2022). Designs will be judged on design criteria, functionality, ingenuity, and presentation quality. Winners will be recognized at an on-site awards ceremony at CPSSC.
This year’s teams are creating a GaN-based 400 V photovoltaic power supply design that uses GaN Systems’ semiconductors to meet the following evaluation criteria:
- A low-cost design with 360 VDC~400 VDC input voltage, 220 VAC output voltage, and total harmonic distortion (THD) of < 3% at 400 VA output.
- Greater than 93% efficiency, 10W/in³ power density minimum, and operate continuously at 25ºC for 30 minutes.
