Research on modeling control module of DC-DC converter for Simulink

Applying co-simulation methods is important to power electronics simulation, which can take full advantages of different software to improve simulation efficiency. Simulink, system-level simulator, is often used to combine with other software to perform co-simulation. Thus, using part models of Simulink to model plays an important role in co-simulation methods. The co-simulation method based on SLPS for DC-DC converters can combine the advantages of Simulink and PSpice. In this co-simulation method, the control module of DC-DC converters should be modeled by part models of Simulink. And modeling control module is a key step to perform the co-simulation. This paper describes how to use part models of Simulink to model the control module of DC-DC converters according to its relevant circuit. The proposed model has been simulated in Simulink environment. By comparison with the simulation result of the relevant circuit using PSpice, the control module Simulink model is validated.
