Abstract
The relationships among maximal resonant current,maximal voltage of capacitor and DC gain,switching frequency,load and resonant inductor ratio that the current of rectifier diodes for LLC resonant DC/DC converter operates in discontinuous mode are analysed in detail.Basing on the derived equations a series of curves are drawn with Matlab software so that an optimal design method for LLC resonant converter parameters are found.Experimental results are presented to verify the theory.
