KUST Team Win the Grand Prize in IFEC 2017

The final round of 2017 International Future Energy Challenge (IFEC 2017) hosted by the Institute of Electrical and Electronics Engineers (IEEE) was held in the Center for Power Electronics Systems (CPES), Virginia Tech, USA in July. After two days of effective presentations, defense and circuit tests, the team from Kunming University of Science and Technology (KUST) won the Grand Prize Award and the Outstanding Thermal Performance Award. The team was led by Assoc. Prof. LI Siqi from Faculty of Electric Power Engineering and the members are all KUST undergraduate students and graduate students.

 

IFEC (official websaite: http://www.energychallenge.org/) is a global competition which aims for innovation, conservation and effective use of electrical energy. The competition is open to any college and university students with engineering backgrounds. It is one of the most high-level innovation competitions in the field of new energy and power electronics,which has attracted hundreds of teams such as Tsinghua University, University of Michigan and so on.

The topic of this year’s competition is “High-Efficiency High-Density Isolated DC-DC Converter” with the following detailed specifications and requirements: 1. Input Voltage Vin: 360~400 Vdc; 2. Output Voltage Vout: 12 Vdc; 3. Output Power Pout: 750W; 4. Efficiency: >97%@50%load; 5. Power Density: >15 W/cm3; 6. Period of Competition: July 25th, 2016 to July 25th, 2017.In October 2016, 23 teams submitted their reports for proposal and finally 10 teams entered the final round.

The final competition was held at the Center for Power Electronics Systems (CPES), Virginia Tech, USA from July 23 to 25. The circuit presented by KUST team reached the highest Power Density: =21 W/cm3, Efficiency: 97%@ full load, sustainable running of 15mins under 55 centigrade degree with Power Output Pout: 500W. Finally, KUST won the Grand Prize Award and Outstanding Thermal Performance Award, and Zhejiang University and National Taiwan University of Technology respectively won the second and third place.

This is the second time that KUST has participated in the event. Back in 2015, the team led by Assoc. Prof. LI Siqi joined the competition for the first time and won the Best Engineering Design Award, ranking second among all teams. Besides, KUST graduate ZHU Liyan’s outstanding performance during the two competitions enabled him to be enrolled in a PhD program of University of Michigan with full scholarship.
