Resilient and Adaptive Power Integrator and Despatcher

This is the authors' abstract. We don't add key points for this paper.

This article introduces resilient and adaptive power integrator and dispatcher, a multi-input multi-output (MIMO) converter topology designed to operate across various voltage levels. Its key advantage over similar converters lies in providing galvanic isolation among all input–output ports, effectively mitigating risks associated with short circuits and lightning strikes while preventing unintended current flow between multiple ports. Incorporating a multiwinding transformer eliminates the need for power electronic switches on the load side by adjusting the secondary-side turns through uncontrolled rectifiers. This streamlined design, managed by a single controller, significantly reduces system complexity while efficiently allocating available power from renewable energy sources and energy storage systems. A comprehensive seven-port hardware prototype has been developed and tested. The experimental results reveal that the proposed MIMO dc converter can effectively handle the power flow between the ports.
