Application of LLC solution in Henryuan switching power supplies and chargers


 Henryuan LLC switching power supply and charger

Henryuan 300W, 420W switching power supplies and chargers are designed with LLC control scheme. The LLC design mainly considers rectification filtering, energy conversion, circuit protection and other aspects. LLC resonant converter is the most important part of energy conversion.

Using resonance technology, there are many advantages in the power conversion process. Reduce the loss of the switch tube, improve the conversion efficiency, have lower electromagnetic interference, and have a wider input and output range.

LLC resonant converter is based on resonant oscillation, mainly composed of input capacitor, transformer, resonant capacitor, rectifier circuit and control circuit. The input capacitor smoothes the input of the power supply and provides a stable input voltage for the subsequent circuit. The coupling effect of the transformer realizes the voltage rise and fall conversion, which is mainly composed of the main coil, the secondary coil and the common mode coil. The resonant capacitor forms a resonant circuit with the main coil and the secondary coil to control the waveform and frequency of the voltage. Suitable resonant capacitors are used to meet the needs of different loads. The control circuit controls and adjusts the LLC resonant converter according to factors such as load requirements and input voltage fluctuations to meet stable power conversion.
