Abstract EN
We establish a novel hybrid model of a continuous conduction mode buck converter with a constant power load based on the mixed logical dynamical modeling method.
Based on the proposed model, the influence of the constant power load’s negative impedance ( R C P L ) on the dynamics of the buck converter with a constant power load is studied by computing bifurcation diagrams and the spectrum of the largest Lyapunov exponents with the variation of the absolute value of R C P L .
Numerical results show that the system’s bifurcations exhibit two different types of behavior, namely, Hopf bifurcations and state jumping.
Moreover, the accuracy and effectiveness of the established mathematical model are verified via simulation and experimental results.
Because of including different discrete mappings of the system exhibited in different working modes in a unified model, the proposed hybrid model solves the problem of choosing different discrete mappings according to different working models.
That is, the hybrid model in this paper provides a new unified model for future research on the dynamic properties and design of controllers for such systems.
