All You Wanted to Know About Ferrite Core Transformers
                     
A transformer is a device used in the distribution and  
transmission of alternating current (AC). It does so by  
stepping up (increasing) or stepping down (decreasing) 
the  voltage to attain the desired values.
To fit its use in a wide range of applications, we divided 
these  into categories based on their phase, core and 
cooling  systems. Below is al you wanted to know about 
the Ferrite  Core Transformer, a type of transformer that 
uses ferrite  cores. To understand that well, let’s answer the 
basic  question:
What are Ferrites & Ferrite 
Cores?
Ferrites are ferrimagnetic ceramic materials divided into 
hard  and soft ferrites based on their magnetic coercivity. 
Hard  ferrites exhibit high coercivity, making them difficult to  
demagnetize and great for applications for permanent  
magnets.
These soft ferrites are used to make ferrite cores. Ferrite cores 
 are magnetic cores that allow easy windings to form 
insulators  and transformers. Their wide range of properties 
like low losses  and smooth working at high frequencies make 
them ideal for  ferrite core transformers.
Ferrite Core 
Transformers
These transformers are made from ferrite cores with  
windings made from ferrites. As the core is made of a  
combination of iron oxides, zinc, nickel, and manganese  
compounds, they flaunt useful properties like low 
coercivity,  low eddy current losses, and high current 
resistivity which  improve the transformer’s working.
Another popular transformer is an iron core 
transformer.  Here’s a brief difference between them:
Ferrite Core Transformer Vs Iron Core 
Transformer
As the names suggest, the basic difference comes 
in  the core.
Iron core transformers have a low Q factor, which measures the  
coils' performance, capacitor inductor (in terms of losses) and  
resonator capacity of the system in a transformer. The other has 
a  higher Q factor.
Iron core transformers suffer from high eddy current losses as  
compared to the low losses in the ferrite core transformers. This 
is  resolved by adding a laminated iron core.
Salient Features
1.Lack of Eddy Currents
Since transformers work on the principle of inductance, there’s a  
varying magnetic field inside that gives rise to a localised electric 
 current known as an eddy current. It negatively affects the 
working  of a transformer. Even at high frequencies, ferrite core  
transformers keep eddy currents at bay, delivering excellent  
performance.
2. Core with Low Coerc vity
The core made from ferrites pave way for low coercivity. This 
helps  the transformer work efficiently as it doesn’t resist that 
constant  change in magnetization.
