Modeling and simulation of Boost converter in CCM and DCM

This paper introduced the operation principle of current mode control boost converter. The equations of two different work states were built by applying the theory of KCL and KVL. Two models working in CCM and DCM were respectively established using Matlab/Simulink and the nonlinear phenomenon of boost converter can be observed through simulation. The results of theoretical analysis are corresponded with simulation and it can confirm these models are correctness and feasibility. It was also studied the change of these parameters impacting on the bifurcation and it can find the change of these parameters impacting on the stability of the converter. So, it can provide a reliable instruction for the stability design of boost converter.
