B-TRAN®

B-TRAN® simplifies bidirectional switching architectures by replacing up to four conventional power semiconductor devices, enabling lower conduction losses, improved power efficiency and power density.

Unlike traditional mechanical breakers, SSCBs using B-TRAN® can interrupt fault currents up to 1000x faster, eliminating arcing and reducing wear.

With ultra-low conduction losses and inherent bidirectional operation, B-TRAN® simplifies system design while improving reliability and performance. Compared to conventional semiconductor solutions such as IGBTs and SiC MOSFETs, B-TRAN® delivers significantly lower losses and supports compact, thermally efficient designs.
