What Types Of Appliances Need Primary Transformers?

A transformer – what is this?

A transformer is considered to be a converter. This is a device which takes advantage of the principles of electromagnetism and converts one voltage or current to another. It is basically made of pairs of wires that both insulated. There are two types of transformers:

  • Step up – this enables the voltage to increase
  • Step down – this does the opposite

Lastly, only DC voltages are compatible with these. AC voltages are totally out of the picture.

The importance of transformers

Transformers are very essential since 1985 as it passes voltages and currents. Without this capability, the kind of current we have and the appliances we are using now may not be compatible with any socket we try to plug it into. These are designed to help increase and decrease voltages. Those electrical devices which obviously need low voltages like cell phones, become possible to charge as the transformer ensures that the voltage decreases despite a number of similar usages. Without them, we may be electrocuted anytime.

Here are transformer symbols you may like to know:

  • Air cored transformer
  • Iron cored transformer
  • Iron cored auto transformer
  • Variac
  • Iron dust cored transformer
  • Variable inductance iron dust cored transformer
  • Iron cored transformer with screen
  • Goniometer
  • Ferrite cored transformer
  • Pre-set inductance ferrite cored transformer
  • Air cored link coupled transformer with coupling varied by a swinging link
  • Alternative symbol for an air cored transformer

What does a transformer consist of?

  • Bobbin
  • Core
  • Windings

Applications of it

  • Mains voltage conversion
  • Switch mode power supplies
  • Electrical isolation
  • Voltage conversion transformer
  • Impedance matching
  • Auto transformer

Given everything that has been mentioned, you will understand how important a transformer is. They are very useful devices and learning to work with them, or even design then can definitely be helpful to you in your daily life. Imagine a world without them, everybody may have died because of electrocution.  You may think this is a complicated science, but really, it is not. You just need to familiarize the kinds of it, the types and the parts. Who knows, in the future, you even may be able to invent your own awesome transformer. We should always be thankful to our knowledgeable scientists in the past who came up with the crazy idea of electricity to begin with and of course, to whoever decided to invent the transformer!
