为了给直流配用电系统中通用适配器的研究提供理论依据,全面地了解直流家用负载的特性尤为重要。对常见的直流家电中的直流阻性家电进行了大量实验测试。通过渐进升高直流阻性家电端电压,记录其端电压及负载电流数据,并对数据进行分析与处理,绘制了直流阻性家电伏安特性曲线以及斜率曲线;根据两种曲线的变化趋势及其规律,对直流阻性家电特性进行了分析与归纳,将直流阻性家电归为两类;基于分类以及两种曲线的特点,提出了三种适用于直流阻性家电通用适配的基本控制构想,为直流家电通用适配器的研究奠定了理论基础,为直流家电自适应适配起到了积极地促进作用,为直流用电技术的发展指引了方向。

In order to provide a theoretical basis for the research of universal adapters in DC power distribution systems,it is particularly important to fully understand the characteristics of DC household loads.A large number of experiments and tests were carried out on DC resistive home appliances among common DC home appliances.By gradually increasing the terminal voltage of DC resistive home appliances,recording its terminal voltage and current data of loads,and analyzing and processing the data,the volt-ampere characteristic curve and slope curve of DC resistive home appliances were drawn.According to the changing trends and laws of the two curves,the characteristics of DC resistance home appliances were analyzed and summarized,and DC resistance home appliances were classified into two categories.Based on the classification and the characteristics of the two curves,three basic control ideas suitable for universal adaptation of DC resistive home appliances were proposed,which lays a theoretical foundation for the research on universal adapters for DC home appliances,plays a positive role in promoting the adaptive adaptation of DC home appliances,and guides the development of DC power technology.
