Learn About Bi-Directional DC-DC Converters For Battery-Banks at APEC 2014

February 28, 2014

apec_150Many systems, from telecommunications infrastructure to hybrid automotives, back up a main power source with batteries. In these applications power architects need to transfer power to and from the batteries.

In these applications, a single bi-directional DC-DC converter offers obvious advantages over separate converters for charge and discharge. Traditional bi-directional converters, however, suffer from voltage spike issues and have limited efficiency and power capabilities, presenting significant challenges when designing higher power systems.

At APEC 2014, Vicor will present “A New High Efficiency Isolated Bi-Directional DC-DC Converter for DC-Bus and Battery-Bank Interface”, a paper by Xiaoyan Yu and Paul Yeaman. The paper describes a solution that not only eliminates the voltage spike issues, but also delivers 300 W at 92.9% efficiency to charge the battery and 1500 W at 93.6% to power the DC bus. The solution can be paralleled, enabling higher power systems.

The presentation will be held during session T18 on Wednesday March 19, 2014 between 2pm and 5pm. Visit the APEC website to learn more.
