中文摘要

本文针对串并联多单元变换器,提出了一种新型多速率调制器。该类变换器在提升效率和功率密度方面具有显著优势,且通过减少滤波器储能需求,实现了更快的动态响应。文章重点探讨了交错控制模式对系统性能的影响及优化方法。

English Abstract

The series and parallel multicell converters have been introduced because they provide benefits in terms of efficiency and power density. However, they also allow reducing the amount of energy stored in the filters, which potentially allows for faster dynamic responses. Interleaving the control patterns of different cells is another distinctive feature of these converters and is also the root of a...
