Modeling and simulation of an integrated magnetic boost converter in continuous and discontinuous conduction mode

In this paper, two mathematical models under continuous and discontinuous conduction mode of an integrated magnetic DC-DC boost converter are presented in order to be employed in a photovoltaic-grid connected charging system of an electric vehicle battery. The operation principle of this converter is detailed and the time-variant state equations of the two different models are built by applying Kirchhoff lows. The modeling technique is based on the switching functions concept and the models are tested under Matlab/Simulink environment. A comparison of transient states of output voltage for two models is included.
