Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents the static and dynamic characteristics of an LLC current-resonant converter. Firstly, considering the fundamental frequency responses of the resonant circuit and the DC gain characteristics of the total converter circuit, the optimum switching frequency for higher efficiency is discussed. Secondly, using the model-based simulation technique, a control transfer function of the LLC resonant converter and a feedback compensator with a photo-coupler and a shunt regulator are examined. As a result, the above control transfer function is estimated as a first-order one composed of a load resistance and a output-filter capacitance. Finally, the dynamic responses of the total LLC current-resonant converter including the voltage feedback loop are compared for a load variation and for some parameters variation associated with the photo-coupler and the shunt regulator.
