Abstract Since resonant switched capacitor converter can realize zero-current switching, reduce switching loss, and improve power density, it is widely used in high power density and gain ratio applications such as data centers and electric vehicles. As an essential part of SCC, the inductor is a crucial factor affecting the improvement of converter performance. To solve the decoupling problem of unequal resonance currents of the front and second stages of the converter, this paper designs the decoupled magnetic integrated inductor without opening the air gap in the center column. Based on the analysis of the working principle of the circuit, compared with the coupled magnetic integration, the decoupled magnetic integration method without an air gap in the center column has a higher inductance coupling degree and can achieve two-stage decoupling. The asymmetry of the resonant parameters of the converter will lead to inconsistent resonant periods of the front and second stages. In this paper, the complete symmetrical winding is used to reduce the influence of the windings on the magnetic parameters, which can effectively ensure the consistency of multiple inductor parameters. Finally, the experimental prototype is built to verify the rationality and effectiveness of the designed resonant SCC magnetic integrated inductor.

Key words： Coupled inductor decoupled magnetic integration complete symmetrical winding resonant switched capacitor converter
