摘要

通过将两个Buck-Boost组合加入耦合电感和升压单元来增强DC-DC转换器的电压增益。同时,通过交错并联的方式控制开关管,进一步降低输入电流的纹波,设计一种双耦合Buck-Boost的交错高增益变换器。该变换器能有效降低开关管的电压应力,也可避免变换器工作于极端的高占空比和匝比情况下。对变换器在CCM模式下的工作状态进行详细分析,对变换器的稳定性能及各项参数进行计算。最终,成功搭建一台功率为250 W的样机,以验证理论分析的可行性。

Abstract

This paper enhances DC-DC converter voltage gain by integrating two buck-boost converters with coupling inductors and voltage-multiplier circuits, while clamping circuits absorb leakage inductance to form a dual-coupled interleaved topology. The design reduces power switch voltage stress and avoids extreme duty-cycle/turn-ratio operation. Detailed continuous conduction mode （CCM） analysis with theoretical stability criteria derivation and a 250 W experimental prototype collectively validate the proposed methodology.
