中文摘要：

发明问题创新理论（TRIZ）作为一种技术创新的方法论,已在诸多领域得到了广泛应用。本文尝试将TRIZ理论与电力电子变换器拓扑研究相结合,系统地提出一种电力电子变换器拓扑的构造方法。本文以单级功率因数校正电路为例,利用TRIZ理论中的冲突矩阵,深入分析了一些典型单级功率因数校正电路的拓扑构造原理,验证了TRIZ理论指导电力电子变换器拓扑设计的可行性和有效性,从而为构造性能更优越的功率因数校正电路提供了思路。

英文摘要：

As a methodology of technology innovation,TRIZ has been widely used in many fields. This paper attempts to combine TRIZ theory with power electronic converter topology research,and proposes a topology construction method for power converters systematically. Single-stage power factor corrector is used as an example in this paper,and some typical PFC circuits have been analyzed thoroughly by applying the conflict matrix in TRIZ,which proves the feasibility and effectiveness of the proposed method,and provides a guideline for designing the power factor corrector with better performance.
