Taking as a starting point the exact feedback linearization to transform a non-linear system into a linear one through coordinate transformation and state-space feedback based on its non-linear model, we have presented in this document the modelling, analysis and non-linear control of a boost-type power converter, with the objective of comparing the results with a proportional, integral and derivative controller. This technique was then applied on a power converter from continuous current to continuous current and the dynamics were analyzed zero to verify the validity of the controller, which was simulated in the Simulink-Matlab software. Finally, the simulation results showed that the system with the exact linearization controller is not only free of excess, but also improves the stability in the output voltage.
