The Modular Multiport Power Converter (MMPC) system efficiently manages and distributes power from multiple energy sources. Each power converter module connects to a common negative bus and can handle different voltages. Power generated by these modules is sent to a common DC bus and partly stored in an energy storage system (ESS). Modules use a phase-shift angle for consistent switching, controlling power flow. Each module has a transformer with primary and secondary windings, and ports for energy sources, the ESS, and a microgrid. The system adjusts to varying conditions and optimizes battery charging through precise control of switching and phase-shift angles.

The challenge is to effectively manage and distribute power from multiple energy sources with different voltages while ensuring efficient storage and transfer to a microgrid. Additionally, there is a need for a system that can adapt to varying environmental conditions and optimize battery charging without being dependent on the number of power converter modules. Ensuring consistent switching and power flow control through phase-shift angles also presents a significant problem.
