Hybrid AC/DC microgrids have become a viable solution for achieving enhanced reliability, flexibility, and efficiency in modern power systems. This paper uses a magnetic network energy router (MNER) to enhance power flow control and stability across multiple DC ports of a quad-active bridge (QAB) converter. A decoupling-based proportional-integral (PI) control strategy is implemented to regulate port voltages and currents in real-time, effectively mitigating transient disturbances and maintaining tight regulation under varying load and reference conditions. This approach is validated on a hardware-in-the-loop (HIL) platform that integrates an OPAL-RT real-time simulator with a Texas Instruments C2000 digital signal processor (DSP). The setup emulates the high-fidelity QAB converter and microgrid dynamics, allowing continuous data exchange and online parameter tuning. Experimental results from multiple scenarios demonstrate that the decoupling-based PI control ensures stable port voltages, precise current regulation, and robust power sharing among all ports. The findings highlight the effectiveness of the proposed control strategy, validated by the HIL platform, in maintaining reliable operation under diverse transient and steady-state conditions, providing a scalable and flexible solution for modern hybrid microgrids.
