Abstract

The invention discloses a low-power household load classification method, which obtains inductive load classification and resistive load classification according to operation characteristics of a low-power household load, and specifically comprises the following steps: judging terminal voltage characteristics and terminal current characteristics when the low-power household load works; if so, carrying out inductive load classification; and if the working voltage / current of the household load presents a linear or approximately linear change trend, the household load is classified as a resistive load. Compared with the prior art, the method provides a theoretical basis and a research basis for the research of the adaptive adjustment method of the DC adapter, and enriches the research and development of the technical field of DC power distribution and utilization.

Description

technical field [0001] The invention relates to a DC power consumption system, the fields of intelligent power consumption technology and DC adaptation technology, and in particular to a classification method for low-power household loads. Background technique [0002] In recent years, with the vigorous development of distributed energy systems and energy storage technology, as well as the large-scale access of DC loads such as electric vehicles and household appliances, the characteristics of DC power distribution systems have become more and more obvious. Gradually obtained a good development prospect. [0003] As a key link in the voltage conversion of the low-voltage DC power side in the DC power distribution system, the DC adapter has great research significance and value in improving energy efficiency, reducing size, and saving costs. A DC adapter is essentially a DC / DC power converter. In the existing low-voltage DC power environment, there are many types of DC load...
