EI transformer is a kind of electronic transformer, which is defined according to the shape of the iron core, because the iron core of the EI transformer is superimposed by the "E" type piece and the "I" type piece, so it is called an EI transformer. EI transformers are generally power frequency (low frequency) transformers (50HZ or 60HZ), power transformers, and some audio transformers are also EI, such as those used in audio.
