Title: PSPICE MODEL OF A SLIDING MODE CONTROLLED DC/DC BUCK CONVERTER
Keywords: buck converter, sliding mode control (SMC), convergence factor

Abstract: The control in high performance DC/DC converters requires not only to ensure system stability but also to achieve a rapid response to sudden changes of the load, to achieve good regulation. There are basically two ways to control the switched DC/DC converters - linear and nonlinear control. Nonlinear control often produces better results but sometimes increases the complexity of the practical implementation of the scheme. Switch-mode power supplies represent a particu-lar class of variable structure systems. Thus, they can take advantage of non-linear control tech-niques developed for this class of systems. PSpice model of DC/DC buck converter controller is designed, based on the classical sliding mode control (SMC) which is a nonlinear control meth-od.
