Abstract
The paper presents the design of a PI digital controller used to control the output voltage of a switched mode DC-DC buck converter. The digital controller is implemented with the help of an 8 bit microcontroller. To derive the control law of the PI controller, the switched mode DC-DC converter is modeled as a linear system using the state variables averaging technique. The authors also present the simulation and experiments results related to the theoretical aspects mentioned in the paper.
