Abstract

The growing insertion of solar photovoltaic (PV) systems in the modern power systems requires high-efficiency, compact and reliable power conversion solutions. The traditional PV conversion system generally uses full-power processed DC-DC converters followed by inverters, which increases conduction and switching power losses, especially at higher power ratings. To overcome these challenges, this paper proposes a partial power processed resonant converter with a dual-mode transformer-less inverter for efficient solar PV power conversion. In the proposed system, only a portion of the total solar PV power is processed through the DC-DC converter stage and the rest of the power is directly fed to the DC link, thus resulting in a substantial reduction in overall power losses. A series resonant DC-DC converter is used to realize soft-switching, which reduces switching stresses and improves system efficiency. The dual-mode transformer-less inverter validates flexible system operation for different PV and loading conditions while ensuring high power quality. The proposed system is modeled and simulated using MATLAB/Simulink and its performance analyzed for various operating conditions. A comprehensive comparison analysis with a conventional full-power processed solar PV conversion system is conducted in terms of system efficiency, power processing ratio, switching power losses, and total harmonic distortion (THD). Simulation results confirm that the proposed system ensures higher conversion efficiency and lower power losses while ensuring compliant power quality, thus making it a prospective solution for high-efficiency solar PV systems.
