It is important to stress that a significant loss of power in the transfer of the same, which may be the result of numerous factors, such as wire resistance and currents through the nucleus, known as eddy current, for example. Thus, a transformer is composed of at least two independent windings, although they suffer the action of the electromagnetic field, which is more intense, in relation to the transformers that have a core of ferromagnetic material. The winding in which the voltage to be transformed is applied is called the primary winding and the winding which achieves the desired secondary voltage.
Transformers, which can also be called detraphos EJMM3710T-5, refer to electrical elements that are intended to insulate a circuit, to increase or reduce a voltage. These elements are also used to cause the necessary impedance between different circuits or as part of filters in radio frequency circuits. Transformers of many types can be found, each of which has a different purpose, construction and size. It can be stated that a transformer needs to transfer all the power from the primary to the secondary, remembering that the primary and the secondary consist of the input and output windings, respectively.
