摘要：
To improve the voltage gain of DC/DC converter, the two-phase interleaved Boost converter is taken as the research object, and the dual-coupling voltage doubling structure is introduced. By combining the secondary side with the voltage doubling unit and the clamp absorption branch, a scalable high-gain coupled inductor interleaved Boost converter is proposed. The converter can continuously improve the voltage gain of the converter by cascading multiple side voltage-doubled structures, and share clamping circuits to absorb leakage inductance energy. The working mode of the converter is analyzed in detail, and the steady-state performance analysis and various performance indexes of the converter are presented in the conclusions. Finally, a 200 W experimental prototype is built, and the results verify that the converter can realize 15-times high voltage gain, low-current ripple at the input side, and low voltage stress of the switch tube. © 2022 Science Press.
