Abstract
In this paper, design procedures and voltage gain characteristics on LLC resonant converter with two transformers are described. Two transformers applied to LLC resonant converter are connected in series at the primary and connected in parallel at the secondary to reduce the unbalance of the primary current. Based on the theoretical analysis and simulation results, considering the characteristics of voltage gain and load variation, prototype of the 400W LLC resonant converter for 50inch PDP TV power module is built and the design procedures through the experimental results are verified.
