Design of Solar Energy Collecting Circuit Based on MPPT Control

Abstract

In order to meet the needs of high efficiency solar energy collection in photovoltaic power generation system, a solar energy collecting circuit based on Boost structure DC/DC converter and MPPT control is designed, and the MPPT control strategies and methods are given. The solar energy collecting capability is improved by Boost structure DC/DC converter, and the output efficiency of photovoltaic cells and the electrical collection efficiency of collecting circuit are improved by MPPT control based on the real time estimation of photovoltaic cells status. The theoretical analysis and experiment results validate that the solar energy collecting circuit controlled with MPPT is easy to implement, and has good effect.
