Abstract <br><br>electricity, modern society has near-dominance of clean energy, continues to improve their own position. Show around it, academic research is also open every day up more for the world's energy shortage with this unavoidable problem, people put their hopes into the electric body. It produces a lot of ways, which laid the foundation for it to produce multi-mode, such as water, wind and other bad use of energy, can be converted into electrical energy reasonable, we can see the development prospects of electricity is very broad. Power generation, substation, electricity, many issues have been large-scale deployment, in which the transformer is a very important subject. <br><br>AC voltage conversion device is a transformer, current and impedance of the primary coil when the AC adapter has a through-flow diagram, a core (or cores) and then generates an alternating magnetic flux induced in secondary coil voltage (or current ). Utilizing the transformer is an electromagnetic mutual induction, the device converting the voltage, current and impedance

Summary<br><br>Electricity, the clean energy that society is almost dominated by today, continues to raise its position. Around it, open academic research is also more and more day by day, in response to the world's energy shortage this unavoidable problem, people put their hopes on the body of electricity. It has many ways to produce, which can be many ways to lay the foundation, such as water energy, wind energy and other poor use of energy, can be reasonably converted into electricity, the development prospects of electricity is very broad. Power generation, power generation, electricity, many subjects have been large-scale development, transformers are also one of the very important disciplines.<br><br>A transformer is a device that transforms AC voltage, current, and impedance, and when there is an AC transformer schematic flow in the primary coil, AC flux is generated in the core (or core) so that the voltage (or current) is sensed in the secondary coil. Transformers are devices that utilize electromagnetic mutual sensing, changing voltages, currents and impedances.

abstract<br>Electricity, which is almost the dominant clean energy in today's society, is still improving its position. Around it, more and more academic research has been carried out day by day. People put their hopes on electricity in the face of the unavoidable problem of energy shortage in the world. There are many ways to produce it, which lays the foundation for its multi-mode production. For example, water energy, wind energy and other energy that is not easy to use can be reasonably converted into electric energy. The development prospect of visible electricity is very broad. Power generation, transformation, power consumption, many topics have been launched on a large scale, transformer is also one of the very important disciplines.<br>The transformer is a device to change the AC voltage, current and impedance. When the primary coil is connected with the schematic flow of the AC transformer, the AC flux will be generated in the iron core (or core), which will induce the voltage (or current) in the secondary coil. Transformer is a kind of device that uses electromagnetic mutual inductance to change voltage, current and impedance<br>
