The Design of High Power LED Driver Power Supply Based on the Pattern of LLC Harmonic

Abstract:

The working principle of LLC resonant converter is analyzed. On the basis of the analysis, a high power LED driver power supply circuit is designed based on LLC resonant model. Driver circuit is two-stage: the pre-driver circuit using boundary-conduction mode controller L6562 achieves PFC function, while the post-stage LLC half-bridge topology provides constant pressure parts. This structure makes the overall efficiency of the circuit is higher. And the simulation experiment of the circuit is carried out and the experimental results verify that the driver power supply can achieve high efficiency, low loss and so on.
