      Abstract: 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.
