EE, EEL, EF-core characteristics and uses description:

EE, EEL, EF-type core is mainly used for high-frequency transformer, according to the working frequency is high or low, can be divided into several grades: 10kHz- 50kHz, 50kHz-100kHz, 100kHz ~ 500kHz, 500kHz ~ 1MHz, 1MHz or more. Under the transmit power is relatively large, power devices generally use IGBT, due to the presence of IGBT turn-off current tailing phenomenon, so the relatively low operating frequency; transmission power is relatively small, you can use MOSFET, the operating frequency is relatively high. The following Deng Hui technicians work more to tell you about EE, EEL, EF-type power cores which were not the same characteristics and uses,

EE, EEL, EF-type power core characteristics: Lead space, easy winding wire. Suitable for a wide range of high frequency, wide operating voltage range, output power, good thermal stability

EE, EEL, EF-type power core Uses: Widely used PBX power, LCD power supply, high power UPS inverter power supply, computer power, energy-saving lamps and other fields.
