Design of Pulsewidth-Modulation Based Sliding Mode Controllers for Power Converters in Discontinuous Conduction Mode

Abstract

Abstract-This paper presents an approach of designing fixed-frequency pulsewidth-modulation based sliding mode controllers for power converters operating in the discontinuous conduction mode. The basic concept and design issues are discussed. Preliminary verification and evaluation of the derived controllers are performed through computer simulations using precise models of the systems.

A Novel Dual Inductor DC-DC Buck Converter

“…Hence, for fulfill of both the requirements, a new converter that combines the advantage of both CCM and DCM converters is developed. CCM buck converter has much improved current handling capability with reduced current and voltage ripple [12]. For this proposed circuit only consider the DC-DC Buck Converters operated in CCM.…”
