中文摘要

级联H桥(CHB)变换器因其高可扩展性,被广泛应用于光伏和储能系统。然而,由于多种原因,三相功率和电压常出现不平衡,降低了系统效率。因此,处理不平衡功率的能力对CHB至关重要。本文提出了一种新的相间功率控制方法,以优化CHB变换器的运行性能。

English Abstract

Cascaded H-bridge (CHB) converters characterized with high scalability have been widely used in photovoltaic and energy storage systems. However, the three-phase power and the voltages are often unequal due to various reasons, making the system less efficient. Therefore, the ability to deal with unequal power is necessarily required in CHB. This article proposes three interphase power control meth...
