摘要
本文提出了工作在连续导通情况下DC—DC开关转换器的快速建模的统一方法。首先论证了丘克电路建模理论的正确性和成立的条件,给出了丘克电路的新模型以及其余DC—DC开关转换器的新模型,同时指出了建模的多样性和统一性。因此,DC—DC开关转换器的建模问题可以把一个变结构系统(VSS)的分析问题转化为一个含复合受控源的电路分析问题。本文所提出的方法比状态空间平均法更方使和优越。
A unified method for fast modelling of DC—DC switching converters in continuous conduction mode (CCM)is proposed in this paper. The validity, condition of modelling theory and new models for Cuk circuit as well other DC—DC switching converter given first. And then the variety and uniformity for modelling are given. Therefore, the problem of modelling for DCDC switching converters is to transfer the problem of variable structure system (VSS)analysis into the problem of circuit analysis containing compound dependence source. The method proposed in this paper is more convenient and better than that based on the state space averaged method.
