GaN-Based Hot-Swappable Multi-Active-Bridge (MAB) Converter
Master thesis project @ TU Delft.
The research aims to design a multi-port DC-DC converter via a single multi-winding transformer, by which multiple sources, storages, and loads in a DC microgrid systems can be interconnected and hot-swapped.
The thesis can be found at this link.
The converter has the following key features.
GaN HEMT based switching bridge guarantees low semiconductor losses and high power density.
A planar transformer with PCB winding minimizes leakage inductance.
Master-slave configuration facilitates decoupled power flow.
Modular ports with different power ratings and voltage ratings are hot-swappable from the live MAB converter.
Adaptive decentralized control independently controls power flow.
