The schematic diagram of the working principle of the transformer is shown in Figure 1. The primary winding and the secondary winding of the transformer are equivalent to two inductors. When the AC voltage is applied to the primary winding, an electromotive force is formed on the primary winding, and an alternating magnetic field is generated. The secondary winding is affected by the primary winding. The induced electromotive force (voltage) that is the same as the change law of the magnetic field of the primary winding is also generated, so the secondary winding outputs an AC voltage, which is the transformation process of the transformer.
