Modelling and stability analysis of DC–DC switching converters is the key step to study, analyze and design switching power supplies. The equivalent circuit model in the continuous conduction mode (CCM) is presented in this paper. The DC/DC transfer functions are derived based on the main circuit model, the compensation network circuit model, and the PWM waveform generator circuit model. The analysis and simulation of the small-signal model are discussed based on it. Finally, DC/DC sample are tested with network analyzer. The results show that the modeling approaches taking converter parasitic parameters into account is feasible, which can help optimize and improve the performance of switching power supply design and efficiency. It has practical engineering value.
