Trans

A conversion device that is inserted between a primary circuit and a secondary circuit in an electrical circuit, 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 can 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 amounts of power to electronic circuits that handle minute amounts of power. In switching power supply circuits, it is used for many purposes, including the conversion of voltage, current, or impedance, as well as insulation between the primary side and the secondary side.
