How to choose high frequency transformer magnetic material?
Considering the section area of the core and the area of the window, the multiple output transformer generally requires a larger window area, and the EE, EI or PQ type magnetic cores are selected to have larger windows and good heat dissipation.
High frequency transformer is more than the working frequency of intermediate frequency (10kHz) power transformer, mainly used for high frequency switching power transformer in high-frequency switching power supply, but also for the high frequency inverter transformer and high frequency inverter in high frequency inverter welder. According to the frequency of work, can be divided into several grades: 10kHz-, 50kHz, 50kHz-100kHz, 100kHz ~ 500kHz, 500kHz ~ 1MHz, 1MHz or more.
First, consider energy transfer;The two is to consider the geometric size constraints;
