基于太阳能光伏发电系统的直流电源分析与设计
Analysis and design of the DC power supply based on solar photovoltaic power systems
摘要
Abstract
To solve the problem of independent photovoltaic power system with respect to low energy conversion effi‐ciency and short battery service life ,the maximum power point tracking (MPPT) technology and optimization con‐trol strategy of battery charging and discharging are adopted to the solar charging system .The designed system uses the TL494 as the core of push‐pull booster circuit to reduce the reliance on sunlight .It can supply power to load by battery booster circuit when there is no sunlight .The designed DC power supply is composed of DC‐DC converter based on Atmega 88 microcomputer and battery booster circuit .The results show that the MPPT charging ways can be optimized to manage the charge and discharge process of storage battery .The efficiency of the designed power system is high .The averaged MPPT charging efficiency reaches 91 .24% ,and the good performance can prolong the service life of battery .The developed push‐pull booster system works stably and has reliable operation performance .关键词
