A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage transformation, impedance transformation, isolation, etc. According to different uses, transformers can be divided into several categories. Today we mainly introduce the applications and advantages of isolation transformers, toroidal Transformers, control transformers, and autotransformers, so that you can make better choices when purchasing.
