摘要: 本文提出一种基于耦合电感和三态开关单元有机结合思想的DC/DC变换器，采用两个耦合电感的一次绕组分别替代传统交错并联DC/DC变换器的两个分立电感，将耦合电感的二次绕组及其融合二极管和电容构成两个独立的倍压单元，实现了高电压增益，同时输入端采用交错并联，不仅减少开关管的电流应力，而且减小输入电流纹波。对其工作原理和性能特点分别进行了分析，结果表明该变换器具有输出电压高增益、低电压应力、低输入电流纹波。
Abstract: A novel DC/DC converter was proposed based on the combination of coupled inductors and three- state switching cell. The primary windings of the two coupled inductors are respectively replaced by two separate inductors of traditional interleaved DC/DC converter; the two voltage multiplier modules are composed of the secondary line windings of coupled inductors and diodes and capacitance to achieve a considerably higher voltage gain. The two-phase interleaved configuration not only reduces the current stress through each power switch, but also constrains the input current ripple. The operation principle and property of the converter are analyzed in detail. The results show that the proposed converter has the characteristics of high conversion ratio, low voltage stress and low current ripple.
