Battery Integrated Modular Multifunction Converter

Technical Summary

Drs. Baljit Riar and Regan Zane, researchers at USU, have developed a modular battery integrated converter with a variety of uses: grid energy storage, battery integrated EV drive train, wind power, energy storage at EV charging stations, microgrids, nanogrids, and photovoltaic farms. The converter has a single stage topology that can easily be configured for AC or DC grids. The modular battery integrated approach provides improved battery control for maximum energy utilization and extended lifetime.


Commercial Applications

This innovation would be especially useful for large scale energy needs, such as renewable energy storage.
