Transformer (transformer) is the electrical / electronics that function to move energy (power) power from input to output or from the primary to the secondary side. The transfer of power from primary to secondary voltage is accompanied by changes either up or down. There are two types of transformer Raising the voltage transformer (stepup transformers) and lowering the voltage transformer (stepdown transformer). If the primary voltage is smaller than the secondary voltage, so-called stepup transformer. But if the primary voltage is greater than the secondary voltage, so-called stepdown transformer.At each transformer has primary windings named input and output is called the secondary winding. Has an iron core transformer for low frequency and high frequency ferrite core or some that did not have a core (air core). When the primary winding given alternating current (AC), the primary windings will be the direction of the magnetic field also magnitnya commute. This magnetic field will ind...
