The working procession of the ZCS Boost converter is analyzed, and the discrete mapping of the converter which is operated under the discontinuous mode is proposed in this artical. Based on this model, the stabilization analysis is carried out, the relationship of some critical parameters and the stability of the boost converter is available. Through simulating integrating Matlab/Simulink (SimPowerSystems)software, simulation modeling is setup and the satisfatory results confirms the the theoretical analysis.
