Transformer


transformers are often called are electronic components that can connect to electricity networks have a wide voltage range for which power can be widely distributed and used to change (increase / decrease) tegangangan electrical alternating current (AC).

It consists of an iron core of the transformer, the primary coil and secondary coil. Understanding the transformer has two terminals, namely input terminals are at the primary coil, and the output terminal located on the secondary coil. With the transformer, generator (380 volts) transmission lines (150 kV) electrical load and the load (220/230 volts) can work simultaneously at different voltages.

The basic form of the sense transformer is a pair of ends of the primary and secondary pair at the end. Part primary and secondary windings email wire is not electrically connected. Both wire wound on a winding core called the transformer core. Typically, the sense transformer core is made of iron plates are joined together to form yard iron. While the high frequency transformer for use in radio circuits using ferrite core (iron powder compacted).



Step-down transformers used in electronic low voltage circuits. This type of transformer primary section we associate with, for example, 220 volts AC voltage in skundernya will then issue a lower voltage.

Step-up transformer is the opposite of a step down transformer which is used to raise teganganlistrik AC. Examples of the use of transformer is on a series of emergency light / emergency lights which turn on when interrupts PLN UPS and the PC. The working principle of a transformer in a DC voltage (direct), which is the battery voltage is converted to AC (alternating) and then increased to 220 volt transformer in order to turn on the lights or interruptions in PC PLN.

Types of transformer other transformer is OT (output transformer) and IT (Input Transformer). Types of transformer are widely used in audio equipment. For high frequency transformer maybe later we will discuss in Radio Frequency (RF) because of their use in more rangkaian2 RF.
