Trans

A conversion device inserted between a primary circuit and a secondary circuit in an electric circuit, which converts the power of the primary circuit into magnetic energy and then back into electrical power to output to the secondary circuit. It has a structure in which two coils—the primary winding and the secondary winding—are wound around a core. Due to its ability to convert voltage and current according to the winding ratio between the primary and secondary windings, it is widely used from high-power transmission and distribution circuits to electronic circuits handling very small power. In switching power supply circuits as well, it is used for various purposes such as voltage/current or impedance conversion, and isolation between the primary side and the secondary side.
