| Abstract: | LLC resonant converter is widely used in front-end DC/DC converter for distributed power system and renewable energy power generation system.The integrated planar of the magnetic components in LLC resonant converter has the advantages of high performance,high efficiency and low cost.This paper outlines an improved design methodology based on the loss.Analysis of the influence of resonant inductor and transformer magnetizing inductance,resonant capacitor through power loss,input voltage variation,no-load operation ensure the optimal performance of the system parameters.Because of the importance of planar magnetics in DC/DC converter applications,the simulation by the finite element analysis software Maxwell with various structures of planar transformer verifies the optimal structure design and implements the precise control of the resonant tank in LLC resonant DC/DC converter. |
