Study on Delay Synchronizing Rectification Control Method of Bi-Directional DC-DC Converter for Photovoltaic System

Abstract:

A novel photovoltaic (PV) system is proposed, which exhibits the advantages of better protection and more efficient control on charge/discharge of the battery. Furthermore, it can realize power management of the system. The key point of power management is how to control the bi-directional converter effectively. Considering traditional soft start strategy would be ineffective for bi-directional converter in the double sources application for the possibility of damaging the power device, a new soft start control method named delay synchronizing rectification control method is proposed. A 500W prototype converter is built to verify the theoretical analysis and the control method.
