Transformers are electrical devices which convert an alternating current of a specific voltage to a different voltage, without changing frequency, by the process of electromagnetic induction. While 'step up' transformers receive low voltage and converts into higher voltage, the 'step down' transformers perform just the opposite function. The energy conversion processes take place through the magnetic core.

As mankind is getting dependent on different electronic components with each passing day, these electrical devices have evolved to become one of the most significant technological booms. These devices supply regular power to electrical instruments and are of two types, namely, high voltage transformers and low voltage transformers. Each of these has specific applications. As the name suggests, high voltage transformers deal with higher power and voltage. These are used in transmitting power to the areas where higher voltage is required for safety issues. High voltage current transforming devices can store electrical energy ranging from 500 to 5,000 volts. Metering, Voltage circuit security, electrostatic industrialized ...
... applications and other technical applications require these kinds of current altering gadgets.

High power transformers can accelerate primary voltage to high energy. Higher to lower level of power alterations that these devices facilitate are commonly used in amplifiers, CRT displays etc.

A low voltage transformer is also termed as a Magnetic Low Power Transformer. Used to supply current in a lower form, these devices provide complete safety to the user. These agents reduce the risk of electric shocks and are used in household equipments to prevent short circuits. These electrical devices transfer electric energy through magnetic coupling through one circuit to the other. The voltage supply of these kinds range from 12 to 24 volts. There are certain benefits of the transformer which make these the choicest options over the other electrical devices. Some of these benefits are:

Can alter electrical energy for consumer use as well as several industrial applications.
Very reliable
Low Cost

If you have been thinking of buying a voltage transforming device, then there are certain things which you need to bear in mind. Firstly, find out the voltage rating on the appliance. If the rating is similar to 100Vto 240V, you can manage it without the current device. If the rating is somewhere around 110V or 120V, then it will need you to buy a Step down current Transformer. So, it is imperative to find out whether your appliance actually requires a current transforming device at all. Secondly, you have to determine the apt transformer for your product. You should always select one as per the wattage rating of an appliance. Always use the device rated 25% higher than the appliance's wattage rating. Thirdly, having selected the right device, make sure you have the appropriate plug adapter. Last but not the least, always seek to purchase the devices from reputed manufacturers.

There are two types of transformer in the market- linear transformer and switch mode power transformer. The transformers design is different. Sometimes it is just referred as ac transformer. Linear transformer mostly used in radio, project kits, VCD and etc while switch mode transformer can be found in Monitor, TV, Fax and so on.

A transformer consists of two or more coils wound on the same core. For power transformers, the core material is usually iron. For a radio-frequency transformer, the core material is usually ferrite or air. The basic property of a transformer is to change AC voltage. A transformer cannot change direct current voltage. A step down transformer has a lower AC output voltage at its secondary winding than the AC input voltage to its primary winding. Conversely, a step up transformer has a higher secondary than primary voltage.
