Study on Optimal Design of Electromagnetic Compatibility for Electronic Transformers

The operating experience shows that electromagnetic interference is one of the main reasons for resulting in the failure of electronic transformers.In order to improve the electromagnetic compatibility of the electronic transformers,the paper establishes its simulation model,and studies the electromagnetic interference in the running of the electronic transformers as well as the measures for improving its anti-electromagnetic interference （EMI） capability based on the optimum structural design for the electronic transformers.Through the simulation research,the paper gives the optimization design of the acquisition unit in the electronic transformers,which is easily affected by EMI.
