This paper introduces a control strategy for a Modular Multi-Active Bridge (MMAB) architecture that extends the single phase shift as a novel approach to enable fully decentralized control of the Modular Active Cell (MAC) on a single, arbitrarily large multi-winding transformer. The MAC aims to provide a fully modular, configurable, and scalable solution for Solid State Transformers (SSTs) and Energy Routers, enabling full power and voltage variability in isolated interconnections of diverse DC networks. A novel modeling approach based on discrete-time state-space is introduced. The model is verified through measurements and simulation, showing high accuracy and prediction capability.
