Principle transformer If there is cash flow in the primary coil, it will arise
changes in the magnetic fluks primary. As a result, the magnetic fluks
filled by secondary changes also, so that at the spindle GGL also occur secondary electrical current. Changes in strong currents at the primary
must continuously. Therefore, the flow through the coil primary must flow back and forth (the change of the flow of time).

Kind of transformer, the Step-Up transformer and the Step-Down transformer.
1. Step-Up transformer.
Step-Up transformer is used to GGL enlarge electric voltage or a source (to increase voltage). Transformer secondary voltage has a high electrical compared primernya voltage. Comparison of the ratio of secondary voltage with the primary comparison is the same as the ratio of the amount of twist on secondary coil and primary coil.

2. Step-Down transformer
Step-down transformer is a transformer for used GGL out a power or voltage source (to reduce voltage source). Transformer has a high voltage electricity than the secondary voltage.

Campare coil
Compare coil (n) is the comparison between the number of winding secondary coil (NS) with converter winding primary coil (Np), n = ns / Np, the comparison with the number of primary winding, secondary comparison of the primary voltage (input) and secondary (output). To
determine how much voltage drop or up we will want, you can use the following equation.
