升压交流模式下混合模块化多电平变换器的设计分析与电容优化

This article offers an in-depth analysis of the hybrid modular multilevel converter (MMC) working steadily under boost ac mode and proposes an improved capacitance design approach reducing its overall capacitance without affecting the performance. This enables more cost-effective and space-efficient applications of hybrid MMC in distribution networks. First, considering the uneven energy distribut...
