Is one devoted to the synthesis of PI controller applies to the fitting of the buck converter in advance of this synthesis , made a theoretical study on the DC / DC Converter Buck was conducted. The behavior of a dc power supply / DC controlled by a PI controller has been simulated using the MATLAB / Simulink software.
