蓄电池充放电管理系统
摘要
描述了光伏电站内模拟蓄电池充放电管理系统的设计。 主要是对双向DC—DC变换器(Bi—directional DC.DC Converter,BDC)的研究,它是直流变换器的双象限运行,可实现能量的双向传输,在功能上相当于两个单向直流变换器。在参考相关书籍的根底上,分析了几种双向DC/DC变换器的拓扑构造,通过对它们的分析、比拟,决定采用双向半桥变换器作为本次设计的双向DC/DC变换器的拓扑构造。根据双向DC/DC变换器的设计要求,确定了双向半桥变换器的元器件参数,加上驱动电路及电流检测之后对整个系统进展了研究。研究包括两局部:硬件设计和软件设计。
关键词:双向DC/DC变换器 双向半桥变换器 驱动电路 电流检测
ABSTRACT
This page represent the design of lead-acid battery in photovoltaic (PV) system. It mainly study the Bi.directional DC-DC Converter(hereinafter,“BDC〞) which is the two—quadrant operating DC—DC converter.It can flows in either direction.Depend in the location of the DC source. On the base of some related books, there analyse several DC/DC converter,through these detailed analysis and comparision, the topologies of the bidirectional Half-Bridg Converte is selected as the topologies of the bidirectional DC/DC to the design demand of the bidirectional DC/DC converter,the parameters of the converter are in the driver circuit and current detection ,we study the whole system which include
two parts :hardware design and software design.
Key words: bidirectional DC/DC converter. bidirectional Half-Bridg Converte
Driver current current detection
