Description

technical field [0001] The invention relates to a circuit structure of a multi-working mode energy-saving power supply socket board, which belongs to the technical field of socket boards. Background technique [0002] As we all know, electric energy is an important secondary energy source, which is used in all aspects of modern society. my country is a power generation country second only to the United States, and about 80% of it is thermal power generation. On the one hand, it consumes a lot of human limited energy resources-coal and oil every day, and on the other hand, it also causes serious pollution to our living environment. . Judging from the mining and consumption speed of primary energy such as coal and oil in the world today, the energy situation is very severe. Therefore, countries around the world are advocating the construction of an ecological civilized society to form an industrial structure, growth mode and consumption mode that save energy resources and pro...
