要約(英語): A five element multiplex resonant (LLCLC) full-bridge DC-DC converter controlled by pulse-frequency-modulation (PFM) is proposed in this paper. The high frequency (HF)-link resonant DC-DC converter proposed herein can perform wide-range output power and voltage regulations with a narrow frequency range owing to an anti-resonant tank which works effectively as a wide-range variable inductor. The advantageous characteristics of the anti-resonant tank provide overcurrent protection in the case of the short-circuited load condition as well as the start-up interval, thus the technical challenges of the conventional LLC DC-DC converter can be overcome, and the reliability of the relevant switch-mode power supplies can be improved. The operating principle of the LLCLC DC-DC converter is described, after which its performance is evaluated in an experimental setup based on the 2.5kW prototype. Finally, the feasibility of the proposed DC-DC converter is discussed from the practical point of view.
