| Abstract(in English) | This paper reports the results of research on small-signal transfer functions of LLC current-resonant DC-DC converters. The target circuit is a resonant converter with a double voltage rectifier circuit on the secondary side and controlled by pulse width modulation (PWM). A model for small-signal analysis is proposed and the analysis is performed based on the model. Although the frequency characteristic was expected to be symmetrical before and after a duty cycle of 50%, the analysis revealed that it was not. It was found that the transfer function of the output voltage can be either first-order or second order depending on the change in duty cycle. |
