Smart Supervisory Controlled Power Converter for Hybrid PV-grid Energy System utilizing Soft-switching Switch-over Technique

Hybrid solar PV systems with battery backup and grid support are more reliable in their ability to provide uninterruptible power supply. However, to convert, organize and synchronize input supplies for a range of load conditions, there is a need of more sophisticated converter and control system. To address the conversion, transition and synchronization issues, an intelligent control and switching method is required. The target of this project is to develop a smart power converter system for a hybrid PV-grid energy system. A new integration of hardware components and software innovations is suggested to convert a DC power to AC, to track PV current, choose the sources of power, and to transfer the supply power at zero voltage and current. A DC-DC converter circuit, a supervisory controller, a switch-over circuit, and a soft-switching circuit are modeled and constructed to study the effectiveness of the proposed system. The system's implementation demonstrates that by utilizing a smart power converter system, issues that could arise during the changeover of the power source could be resolved.
