Modeling and simulation of converters Buck, Boost, Buck/Boost and Cuk using cascade control

The design of power electronic converter circuit with the use of closed loop scheme needs modeling and then simulating the converter using the modeled equation. This can easily be done with the help of state equations and MATLAB/SIMULINK as a tool for simulation of those state equations. An attempt has been made in this paper to simulate all basic non-isolated power converters. So that these models can be readily used for any close loop design (say using PI, fuzzy, or sliding mode control etc.).
