DC DC Converters without isolation model

DC DC converters simulink model and design

With this files is possible to calculate and simulate a buck, a boost or a buck-boost converter. There is a .m file with the design parameters (Init.m), that parameters can be changed by the usser, and to simulate the converters this file must be executed previously. In other hand, there is a matlab function with the calculations (this file is called from Init.m).
Finally, there is a model of the three converters. It is possible to add a controller to the model or change the load type (in the attached file, a resistive load is considered).
