Abstract

This paper presents a new modified sliding mode controller with the constant switching frequency .New proposed method using reaching law to obtain steady state response and reducing chattering phenomenon for line and load variations of DC-DC Buck converter. This paper gives a sliding mode controller accessibility condition and control equation according to the calculations.Simualtion results shows that performance of the converter agrees with the theoretical design.
