The non-isolated Bi-directional DC-DC Power Converter (BDPC) of Internal combustion-Linear Generator integrated Power System (ICLGIPS) which mainly used in Hybrid Electric Vehicle (HEV) has the characteristic of dynamic and nonlinear system wide range of voltage change and precise controlled, this will most likely require a wider range of duty cycle adjustment and feed forward of the input voltage for faster response, the accuracy of converter model is very important for designing of control system. In order to achieve accuracy modeling of the converter, prototype topology structure of non-isolated BDPC is analysed. In this paper the method of using average model switch network to build the converter model is presented, so complicated state equations are need not to be established. The details of the method are shown, and a comparison between average model switch network and state equations method is given, the models are simulated using MATLAB/SIMULINK. The simulation results have a distinction between the two models with average model switch network and state equations separately. Conclusions can be drawn: the average model switch network is very different from prototype topology structure of converter, and the simulation results of average model switch network is more identical to practical system, so it is more valid for guiding design of control system of converter. The results obtained here may provide some theoretical guidance for the development and optimal design of some kinds ofpower converters.
