要約(英語): In this paper, the operation characteristics of a novel LLC-type series resonant converter topology having secondary resonant inductors is presented. Because this converter uses parasitic inductors and realizes high-frequency operation, the size of the converter can be reduced. The operation of both the proposed topology and the conventional one was compared using first harmonic approximation analysis. The results of the analysis revealed that the proposed topology has higher boost capability than the conventional one. Based on the analysis, a 12V, 84A output prototype converter was designed, and it was proven that 2.73kW/l output power density and 95.1% efficiency could be achieved.
