Super ER high frequency transformer work for lighting , chargers, led driver, pcb etc. 

There are many types of high frequency transformers, including oscillating coils, mid-cycle or intermediate frequency transformers, power synthesis impedance matching transformers for transmission, high frequency signal ratio matching transformers, and power transmission transformers for switching power supplies. Winding high frequency transformer and its work content are related to the selection of materials, magnetic core and technology. No power requirement of QA wire winding, vibration has silver plated, multi-stranded, single-stranded wire winding, transmission of multi-stranded and high temperature and Q silver-plated wire winding, switching power supply frequency high transformers also need multi-stranded wire winding. General high frequency class transformer requirements of high Q low loss.

The power tube is one of the devices with large calorific value in the high-frequency switching power supply. Reducing its calorific value can not only improve the reliability of the power tube, but also improve the reliability of the switching power supply and improve the mean trouble-free time (MTBF). The calorific value of switching tube is caused by loss, which is composed of switching process loss and on-state loss.
