      In order to further improve the key performance of the basic cascaded Boost converter, a magnetic integrated switched capacitor high gain cascaded Boost converter is proposed. The converter utilizes two voltage doubling units of the split switch capacitor to recombine with the pre-stage energy storage structure of the cascade converter, and simultaneously applies magnetic integration technology to achieve high voltage gain while reducing the switch. The voltage stress of the tube and the inductor current ripple. The working modes of the converter are analyzed, the performance parameters are derived, the magnetic integrated design scheme is given, and the correctness of the theoretical analysis is verified by simulation and production of the prototype.
