Implementation of one cycle control technique in Dc-Dc buck converter

Abstract

A nonlinear control technique is used to controls the duty ratio (T) of a switch in switching converters. i.e., an improved one cycle control technique which is conceptual to the concept of technique of one cycle control. This one cycle control method gives firmness to the source side disturbances, but this technique shows infirmness with the load side disturbances. The proposed new improved one cycle control technique rectifies the drawbacks of one cycle control technique. It strongly rejects both source side disturbances and load side disturbances. Simulations with the buck converter results using MATLAB are given to verify the proposed work. To implement and demonstrate the feasibility of this new control technique over the disturbance, an experimental buck converter prototype has been designed, built, and tested.
