In AC networks, safety is ensured by mains transformers, fuses and circuit breakers. A fault in one part of the system rarely shuts down the entire network. In modern DC networks, such as microgrids, renewable systems and electric vehicles, this natural separation is often missing. A single fault or short circuit can therefore lead to complete system failure and damage to connected components.
The Dual Active Bridge (DAB) is the solution here: a galvanically isolated DC-DC converter that safely transfers bidirectional power. Thanks to Gallium Nitride (Gan) MOSFETs, the DAB can operate efficiently and with a high switching frequency, making the system more compact and energy-efficient.
In this presentation:
- AC vs DC: Why Galvanic Isolation in a DC Network is Crucial.
- What is a Dual Active Bridge and how does it work?
- How GaN MOSFETs enable efficient, compact power conversion.
