Stability Criterion about Cascaded System of DC-DC Converter Based on Their Group Characteristics
摘要
Abstract
Stability analysis about cascaded system of power converters is an unsolved problem yet, the impedance ratio criteria applied in linear circuits is not suitable for analysis and study on cascaded systems of switched circuit. Therefore, this paper introduces group theory which researches symmetry into analysis of cascaded system of DC-DC converters, defines their group set, discusses their group characteristics, reveals the relationship and physical significance between their group and cascade characteristics. As a result, this paper develops a stability criterion about cascaded system of DC-DC converters based on group characteristics, gives a novel mathematical tool to solve stability problem of cascaded system of DC-DC converters.关键词
