基于奇异摄动法的串联光伏构网型变流器控制设计

Modular architectures that consist of several series-connected dc–ac converters have been a focal point of recent innovations in transformerless medium-voltage applications. In this article, we consider an architecture consisting of dc–ac modules containing a quadruple active bridge dc–dc converter, which generates three floating dc links that feed grid-side dc–ac inverters. Practical implementati...
