Abstract

With the growing demand for onboard power in aircraft, the role of energy storage batteries becomes increasingly critical. In this context, the utilization of multiple battery packs supplying power on the aircraft necessitates sophisticated control strategies. The paper proposes a decentralized control strategy tailored for the multi-active bridge (MAB) converter, aiming to ensure the state-of-charge (SOC) balance of batteries connected to the MAB. Unlike conventional centralized control strategies typically employed for MAB converters, the decentralized approach offers enhanced reliability and flexibility. By distributing control functions across the system, this strategy mitigates the risk of single-point failures and adapts more efficiently to dynamic operational conditions. Through comprehensive simulations, the effectiveness of this decentralized control strategy is rigorously demonstrated, highlighting its potential to address the evolving requirements of modern aircraft power systems. This innovation not only enhances the performance and resilience of energy storage systems but also contributes to the advancement of sustainable aviation technologies.
