This paper presents a unified hybrid model with two level networks for peak current mode controlled buck-boost converters operating in continuous conduction mode (CCM) and discontinuous conduction mode (DCM). It is a network model with two levels in which both a detailed switching model and a small signal average model are included correspondingly. The nonlinearity of some electronic components and the parasitical effects of circuit elements are considered The nonlinear inductance is calculated by finite element analysis (FEA). The dynamical performance of the buck-boost converter can be obtained from the detailed switching model in the first level network, and then the frequency domain performance can be obtained from the average model in the second level network. As an automatic mechanism of exchanging data between two models is proposed, all the performances can be obtained automatically. By implementing the proposed model in Simulink surrounding, both the large signal transient performance and the frequency domain behavior of converters are obtained efficiently.
