EF20 2+5 PINS Widening Size Transformer

Description

EF20 high frequency transformer has the characteristics of small size, low price and high reliability. EF transformers are basic ferrite cores. They are widely used in switching power supplies and a variety of electronic circuits. The oscillation modes are full bridge, half bridge, single-ended, and resonant. They have excellent material characteristics. Suitable for the typical transformer structure, the EF type magnetic core increases the cross-sectional area of the magnetic core, which can reduce the overall volume of the power supply as much as possible, which is conducive to small
Shaped, can increase output power, suitable for various switching power supply transformers and choke coils

Application:

High frequency transformer is the power transformer whose working frequency exceeds the medium frequency (10kHz). It is mainly used as high frequency switching power transformer in high frequency switching power supply, but also used as high frequency inverter power supply and high frequency inverter welding machine.According to the working frequency, it can be divided into several grades: 10khz-50khz, 50khz-100khz, 100kHz~500kHz, 500kHz~1MHz, 1MHz or above.In the case of large transmission power, IGBT is generally used for power devices. IGBT has a phenomenon of turn-off current trailing, so its operating frequency is relatively low.The transmission power is relatively small, can use MOSFET, the operating frequency is relatively high.
