High power EQ high frequency transformer with excellent performance 




2. What are the commonly used magnetic cores of EQ high-frequency transformers?


The seven magnetic cores commonly used in EQ high-frequency transformers are for your reference. They are pot type core,RM type core,E type core,EC, ETD and EER type core,PQ type core,EP type core, ring type core and so on. They are analyzed for you.


1. Can type magnetic core

The skeleton and windings are almost completely wrapped by the core, resulting in a good EMI shielding effect. The size of the grooved core conforms to IEC standard and has good interchangeability in the manufacturing industry. Can provide a simple framework (PIN) and PCB mounting skeleton (PIN); The size of the core and other types is greater than the cost due to the shape of the tank design; Due to its shape is not conducive to heat dissipation, it is not suitable for large power transformer applications.


2. Type EP core

The EP type magnetic core's circular central column three-dimensional structure completely wraps the winding except the end in contact with the PCB board, which is well shielded. This unique shape minimizes the effect of air gaps on the contact surfaces during assembly of the two cores and provides a greater volume and overall space utilization ratio.





Ask:  Is the greater volume with greater power of the switching power supply  ? How large power switching power supply can be called a large power switching power supply?

Answer:  This  does not have a regulation, big is a relative concept, individual understanding, 1KW to tens of thousands of KW can be called big.
