This letter proposes novel multielement resonant converters, which are improved topologies of the conventional LLC resonant converter, for voltage step-up applications. A notch filter is introduced into the secondary side of the LLC resonant converter. The voltage gain of the proposed resonant converters can be as low as zero with limited switching frequency range. Therefore, the start-up and short output circuit protection issues of the conventional LLC resonant converter can be solved with the proposed solutions. Furthermore, the circulating energy of the resonant tank can be reduced as well. In comparison with the multielement resonant converters with a notch filter on primary side, the proposed converter can help to reduce the conduction losses associated with the notch filter and provide higher voltage gain at the resonant frequency. The topologies and characteristics of the proposed resonant converters are analyzed. Experimental results are given to verify the effectiveness and the advantages of the proposed solutions.
