Abstract

This paper presents a comprehensive study about the application of three control methods in DC/DC converters. Fuzzy, proportional-integral and fixed frequency sliding mode controllers are applied to DC/DC buck converter. Fixed frequency sliding mode controller is studied with two different design approaches. Advantages, disadvantages, similarities and design procedures of controllers are studied. The dynamic performance of these controllers under input voltage change and load current variations are presented.
