原始语种摘要: This study presents a novel family of dual-transformer multi-resonant DC–DC converters (DTMRCs) with a resonant zero point (RZP). The limitations of the conventional LLC resonant converter and its fundamental harmonic approximation (FHA) method are firstly discussed. On this basis, a unique RZP is combined with the dual-transformer architecture. As a result, both of the output voltage regulation capability and the over-current protection feature are promoted. Then, an extended describing modelling method is presented to improve the calculative accuracy of the FHA method. Moreover, by means of the appropriate placement of all three resonant frequencies, the fundamental and the third-order harmonic components are employed to transmit active power to the load simultaneously. The zero-voltage...
