Multiphase paralleled circuit topology is widely used in the field of engineer application for the cause of increase output power of the DC converter, while the corresponding small signal model and stability analysis are rarely studied. In this paper, a discrete small signal modeling method is proposed for a digital control multiphase paralleled DC converter. Different from common average circuit model, this modeling method takes the switching action with IGBT into account, beneficially the phase difference between multiple paralleled circuit can be considered. Accuracy of the method is verified by Simulation by MATLAB/Simulink, and the stability analysis is carried out using this model.
