负载动态下的级联系统大信号稳定性分析
Large-Signal Stability of Cascaded System under Load Transient
摘要
Abstract
The cascaded power electronics system is one of the most popular configurations in the real applications.In large scale or complex power supply systems,the stability for cascaded system including small-signal stability and large-signal stability is the key factor for reliable operation.This paper focuses on the large-signal stability of cascaded power electronic system under load transient,and clarifies the distinct difference from small-signal stability.Based on two cascaded voltage mode Buck converters,the small-signal stability and large-signal stability of the system are analyzed,and an analysis method for large-signal stability is proposed in this paper.With the proposed analysis method,the large-signal stability of cascaded system under load transient can be analyzed and designed.The simulation and experimental results verified the analysis method.关键词
