| description | The invention discloses an LCLCL high-order DC converter based on stacked bridges and a control method, and belongs to the technical field of power converter design. The problems that the voltage input range of an existing LLC resonant converter is limited, and voltage input fluctuation is likely to be generated are solved. The converter comprises a switching tube S1, a switching tube S2, a switching tube S3 and a switching tube S4 which are sequentially connected to form a stacked bridge; a band elimination filter, a primary side of a transformer T, a resonant inductor Lr and a resonant capacitor Cr are sequentially connected between an upper bridge arm and a lower bridge arm in series; one end of the secondary side of the transformer T is connected with the anode of a diode D1, the cathode of the diode D1 is connected with the cathode of a diode D2, and the anode of the diode D2 is connected with the other end of the secondary side of the transformer T; an output capacitor C0 is connected between the center |
