1. How to choose high-frequency transformers?


The selection of magnetic core material and core structure of high-frequency transformer magnetic material selection criteria are high initial permeability I, low coercivity Hc, high saturation magnetic induction intensity Bs, low retentivity Br, high resistivity rho and high Curie temperature point. High permeability, the transformer work excitation current is small; When the coercivity is low, the hysteresis loss is small. High saturation magnetic induction, low remanence, transformer magnetic flux changes when work scope of the choice of the form of a magnetic core structure is to consider the energy transfer, the second is to consider the limitation of geometry size, the third is to consider the proportion of core area and the area of the window, multiple output transformer generally requires a larger window area, choose EE, EI core or PQ type, can be larger window and good heat resistance, DC/DC module power supply can choose FEY, FEE, EUI type, such as the transformer fluid flow to the core area is larger, can choose GU core form; In addition, the installation, processing convenience and cost of the transformer should also be considered. At present, GU shaped magnetic core is usually used for medium and high power. This magnetic core features a large sectional area and small magnetic flux leakage.








  • Note:

  • 1. in order to facilitate our production samples and accurate quotation, provide product information more detailed, the better, the general should contain information: product size figure, design, process, test indicators, orders, etc., best can provide sample, customers can through the Email, Fax, Skype, Wechat send the form of product information to us, see our contact information.

2. About the samples, we will provide the samples to you after you confirm the quotation, we will charge the samples due to spend some of the labor cost. we wil make the bulk order after you caonfirm the high frequency transformer samples.


3. About the after-service, for any problem you can contact us any time. we will try to resolve it as soon as possible.


4.some customers always request us send them the transformer drawing and specification, but no any standard parameter, all transformers are different. because different transformer use for different application. do you know that ?
