Abstract(in English) The authors previously proposed derivation method for LLC current resonant converter by using numerical calculation. However, it took a long time and there are some disadvantage that it was hard to use for power supply designers, because it was done manually by the derivation process. Therefore, in this paper, in order to solve these problems, we examined the automation of derivation method by using circuit simulator, PLECS, and Numerical calculation software, MATLAB/Simulink. As a result, it was conformed that the transfer function with equivalent accuracy in a shorter time.
