Abstract

To satisfy the demand for the development of intelligent and digital power grid

more and more electronic devices have been put into the power grid

which leads to the increasingly severe electromagnetic environment of electronic transformers. In order to improve the reliability and stability of electronic transformer operational

the electromagnetic compatibility（EMC） research situation of electronic transformers are analyzed. First of all

the study background of electronic transformers EMC is introduced. Then the electromagnetic interference mechanism and the electromagnetic interference of electronic transformers are mainly analyzed. The anti-interference methods are put forward and the methods of shielding and filtering are discussed in detail. In the end

the problems existing in the EMC current research of electronic transformers are summarized and a macro outlook of its development trend is made.
