Bidirectional Converters for Energy Storage

Gallium Nitride (GaN) significantly improves the performance of bidirectional energy storage converters through its high-frequency operation, low conduction losses, and robust surge capability. It increases conversion efficiency to 95%–98%, reduces system losses by 40%, and achieves higher power density (30%–50% volume reduction), enabling reliable fanless operation. Furthermore, GaN supports efficient bidirectional power flow for applications including solar energy storage, V2G, and portable power systems, accelerating the trend toward high-efficiency and compact energy storage solutions.
