中文摘要

本文提出了一种模块化互联滤波器构建模块(FBB),可在单通道及多通道(并联三相变换器)配置下运行,且不损失对任何谐波分量的衰减性能。研究重点在于耦合电感(CI)与升压电感的设计,通过间接耦合实现模块化交错运行,优化了变换器的滤波性能与功率密度。

English Abstract

This article presents the analysis and realization of a modular interconnected filter building block (FBB) operating under a single and multichannel (parallel three-phase converter blocks) configuration without loss of attenuation to any harmonic components. Emphasis is on the design of coupled inductor (CI) and boost inductor. In order to achieve a modular scheme with interleaved operation, indir...
