LLC (two inductors and one capacitor topology) transformer

Description

With the advancement of science and technology and the development of electronic technology，More and more electronic devices require the use of transformer components。LLC (resonant) transformers are characterized by their ability to simultaneously operate at no load and reflect light or heavy loads with resonant channel current，It embodies the incomparable advantages of ordinary series resonant transformers and parallel resonant transformers.，Therefore it has been widely used。

Advantages：

LLC transformer is an improvement on the traditional LC second-order resonant transformer，Added parallel inductance。Has a high switching frequency、Low switching losses、Allows wide input voltage range、High efficiency、light weight、Low EMI noise、Advantages such as low switching stress。But as the installation space shrinks，Higher requirements are placed on the size of LLC transformers。

LLC transformers produced by Yamaxi，In addition to the above advantages，Also has a smaller size、More power，Therefore, the power density is high。in addition，High accuracy with leakage inductance、High reliability、High stability、High consistency and other features。Detailed advantages are as follows：

(1)Leakage inductance can be controlled within 1%-10% of the main inductance；Leakage range can be controlled at 5%

(2)The magnetic core has good electromagnetic coupling，Simple structure，High production efficiency；

(3)High working frequency，High power density，Frequency is around 50kHz~300kHz。

(4)Excellent heat dissipation characteristics，Has a high surface area to volume ratio，Hot aisle is short，Easy to dissipate heat。

(5)High efficiency，The special geometric shape of the magnetic core structure can effectively reduce core losses.。

(6)Low electromagnetic radiation interference。Low power consumption、Low temperature rise、High efficiency
