Trans

In electrical circuits, a device inserted between the primary circuit and the secondary circuit that converts the power of the primary circuit into magnetic energy, then converts it back into electrical power and outputs it to the secondary circuit. It has a structure in which two coils, a primary winding and a secondary winding, are wound around a core. Because it has the characteristic of being able to transform voltage and current according to the turns ratio of the primary and secondary windings, it is widely used in applications ranging from power transmission and distribution circuits that handle large power to electronic circuits that handle minute power. In switching power supply circuits, it is also used for many purposes, such as converting voltage, current, or impedance, and insulating the primary side from the secondary side.
