[0002] A transformer is a device that converts AC voltage, current, and impedance. When AC current flows through the primary coil, AC magnetic flux is generated in the iron core (or magnetic core), inducing voltage (or current) in the secondary coil. A transformer consists of a bobbin, an iron core (or magnetic core), and a coil. The iron core is mounted on the bobbin, and the coil is set on the bobbin. The coil has two or more windings. The winding connected to the power supply is called the primary coil, and the remaining windings are called secondary coils.
