Abstract: Comparison analysis of sliding mode controlled dc-dc buck converter for chattering suppression with traditional and proposed reaching laws. A proposed reaching laws and traditional reaching law applied to SMC DC-DC buck converter, the proposed reaching law effectively reduces the chattering, because switching devices are existing in the model, it reduces the switching losses in the switching devices of the dc-dc buck converter. The results of proposed reaching law are compared with traditional reaching law. Proposed method gives less switching losses, in turn efficiency of the buck converter increases, more chattering mitigation by proposed reaching laws as compared to traditional reaching law. And very less sensitive in line and load variation. Simulation done in MATLAB.
