In accordance with the growing need for power conversion systems that are efficient and multifunctional, this project introduces a multi-port DC-DC converter that integrates photovoltaic (PV) panels, batteries, and DC grids. The system designed in this approach includes a Single-Ended Primary Inductor Converter (SEPIC), a bi-directional converter, and an inverter circuit, providing continuous energy management. The SEPIC converter steps up or steps down the input voltage efficiently to ensure a stable power supply. The bi-directional converter allows for power exchange between the battery and the grid to support controlled discharging and charging operations. The inverter module also converts DC power to AC, which makes the system applicable to traditional AC loads. The multi-port architecture increases the flexibility of the system, allowing optimal power distribution between multiple energy sources and enhancing the overall efficiency and reliability. This is the best solution for renewable energy use, smart grid, and hybrid energy storage devices, leading to sustainable and resilient power management.
