Abstract

The key to expand PV application is cost cutting and performance enhancing for the extensive application of stand-alone PV generation system. In this paper, the improvement of general efficiency is considered. The new configuration with several DC-DC modules is designed. The conversion steps are decreased and system conversion efficiency is increased. The dual-module MPPT coordinate control is designed to increase PV utilizing efficiency. The battery management is optimized for better performance and longer life time. The performance and total efficiency of PV generating system can be improved for stand-alone load. The experimental results of the prototype verify the effectiveness of proposed protocol and strategy.
