What Is An EI Transformer And Is This A Good Choice To Use Or Not? February 19, 2022

Although every transformer works in the same manner of generating and transmitting the voltage into one or more electric elements, different transformers have different capacities to work. The role of transformers is to balance the voltage and enable safe, economical, and reliable generation, transmission, and distribution of electricity at significant voltage values. Generally, there are two types of transformers i.e. Distribution Transformers and Power Transformers. However, the different types of transformers refer to the differences in transformers concerning the size, material, shape, and quality of performance. So, let’s get into the details of the EI transformer and why you should use it.

EI transformers are named because of the core which is combined by lamination-shaped “E” and “I”. The transformers are economical and traditionally used in a variety of audio applications and electronic equipment. The transformers have an air gap between the E and I lamination which can be easily adjusted by filling it with an appropriate medium to make it suitable for building chokes and output transformers. This application makes the transformers widely used in designing audio output transformers and chokes.

EI transformers have the best application in electronic mediums. Hereby, the following are the absolute reasons to use EI transformers -

  1. The transformers have a simple structure which makes them easy to manufacture. That's why most transformer factories manufacture EI transformers which makes them easily available in the market.
  2. The components for manufacturing the components are easily available and economical making EI transformers economical and easy to make.
  3. Its cores are flat stamping that does not require any kind of forming or bending, making manufacturing easy and economical.
  4. The lamination between cores is easy to remove from a single rectangular sheet without any substantial wastage.
  5. It has a simple method of mounting. It does not require more technical complexities to mount and use.
  6. EI transformers have more surface space between the cores that's why they are more preferred than U, C, and L types.
  7. The structure of EI transformers is held conveniently with simple corner fixing or vacuum impregnation with lacquer.
  8. The transformers hold perfect magnetic coupling between the two ends of the core.

The reason that can restrict you from using EI Transformers:

Every coin has two sides likewise despite having many good qualities it has a drawback that the cores don’t have self-shielding. There are so many benefits associated with that can be used for power, differential, telecom inductors, inverter transformers, and converters. You can make the best choice of electrical devices by buying such REACH AND RoHS compliant EI transformers that can lower the voltage exact value required by your electrical appliance ensuring it is right and safe.
