Trans

A conversion device inserted between the primary circuit and secondary circuit in an electrical 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 with a core wound with two coils: a primary winding and a secondary winding. Due to the ability to convert voltage and current depending on the winding ratio between the primary and secondary windings, it is widely used from power transmission and distribution circuits handling large amounts of electricity to electronic circuits dealing with very small power. In switching power supply circuits, it is also used for many purposes such as converting voltage, current or impedance, and isolating the primary side and secondary side.
