    Abstract: Owning to its high efficiency characteristic, resonant converter is designed to operate at resonant frequency as a DC transformer (DCX), where the transformer turns ratio is designed based on the nominal input and output bus voltages. However, limited by the number of printed circuit board(PCB) layers and turns, it is difficult for planar transformer to achieve non-integer turns ratio. The common solutions include fractional-turn transformer and matrix transformer, but neither method can achieve non-integer turns ratio without increasing the number of turns. This paper proposes a reluctance-controlled arbitrary non-integer turns ratio planar transformer structure. The proposed structure splits the center column, and primary windings are wound on two columns and connected in series. By adjusting reluctance ratio of two columns, the proposed method can achieve arbitrary non-integer turns ratio with fewer turns. Finally, a 30 V/12 V 120 W LLC DCX converter is built to verify the feasibility of the proposed method. Compared with the traditional solution, winding loss is reduced by 1.164 W under full-load, the peak efficiency and full-load efficiency are increased by 0.43% and 1.08%, respectively.
