With every transformer performing the same task of trading voltage for current in a circuit, without affecting the total electrical power, different types of transformers work differently to achieving the same goal. Also, different types in regards to the shape, size, material, etc. also affects the quality of performance. In this blog today, we’ll speak about one particular kind of transformer – the EI transformer.
What is EI transformer?
As the name itself suggests, EI transformer is one whose core is combined by laminations shaped “E” and “I”. A traditional and economical transformer, the EI transformer is widely used in a variety of electronic equipment and audio applications. The air gap between the E and I laminations can be easily adjusted by filling it with a suitable medium, making it suitable for building output transformers and chokes. This is the reason why many audio output transformers and chokes are designed with the EI transformer.
Why should you opt for an EI transformer?
EI transformers have a very simple structure, making it absolutely easy to manufacture, which is why most transformer factories are able to manufacture these transformers.
It is very easy to find the components required to build an EI transformer in the market, making it an easy-make as well as economical solution. With everything being available easily, the prices automatically go down.
EI cores are flat stampings with no need of any kind of bending or forming, which makes it very economical to manufacture.
The laminations can be removed from a single rectangular sheet without substantial wastage.
The mounting method of the EI transformer is simple.
EI transformer cores are more preferred than other U, C, and L core types, mainly because more surface space is protected by the winding in these cores.
The make of an IE transformer is such that the whole thing can be held together conveniently with simple corner fixings, or just vacuum impregnation with lacquer.
There is very good magnetic coupling between the two ends of the core.
Are there any disadvantages of using an EI transformer?
Just like anything else, EI transformers, in spite of having so many good qualities, also have drawbacks. One major drawback is that these cores don’t have self-shielding quality in them.
After going through the blog, it’s time you decide as to whether you would want to use an EI transformer for your application or not. Despite the fact that an EI transformer doesn’t have self-shielding, there are so many other benefits associated with it. So, whether it is for differential, power, or telecom inductors, converters, or inverter transformers, if EI seems to be the right choice for you, you could approach Miracle Electronics for the same. They’re the most reliable EI transformer manufacturer in India, where you can get durable and highly efficient transformers that come with superior wiring, varnishing, and connection terminators, all of which provide excellent regulation with minimal temperature rise. You can thus make the most of your electrical devices by buying such RoHS and REACH compliant EI transformers that can lower the voltage exactly to a value that is required by your appliance, while keeping it running right and safe.
