High Efficiency and High Power Density Isolated Bidirectional DC-DC Converter for Residential Energy Storage Systems

This year we designed and constructed a bidirectional DC-DC converter with high energy efficiency and power density for energy storage system applications. The competition requirements stipulated that the power of the device should be 1 kW, with an output voltage of 400 V and a variable input voltage ranging from 35 V to 50 V, along with a required efficiency of over 92%.
In the final in Beijing, China, we secured the fourth place and yet again won The Educational Impact Award.
