In the present work, the operating principle of the sliding mode control applied to current converter modules with buck typology (reducers) will be shown, for which the equations that describe the dynamics of the system will be found, calculating the surface on which they slide. By means of the Matlab - Simulink software, the simulations of the proposed schemes will be carried out and they will be tested with the variables that determine the robustness kp, and ki (proportional and integral constants) of the system as well as the behavior of the system and the response of the controller against variations. of the load. Then the graphs of the behavior of the main parameters such as current, voltage and output power, duty cycle and power in the inductor are presented. For the purpose of analysis, tests will be established that seek to determine the robustness of the system by varying the power required by the load connected to the system, and test different parameters that achieve the desired response of the system.
