SLIDING MODE CONTROL BASED ON FRACTIONAL ORDER CALCULUS FOR DC-DC CONVERTERS
The aim of this paper is to design a Fractional Order Sliding Mode Controllers (FOSMC)for a class of DC-DC converters such as boost and buck converters. Firstly, the control lawis designed with respect to the properties of fractional calculus, the design yields an equiv-alent control term with an addition of discontinuous (attractive) control law. Secondly, themathematical proof of the stabilit...

متن کاملIsolated Three-Phase Rectifier Using a Sepic DC-DC Converter in Continuous Conduction Mode For Power Factor Correction
This paper presents an analysis of a three-phase rectifier with high power factor using a Sepic DC-DC converter operating in continuous conduction mode (CCM). The structure is particularly simple and robust. Its main features are: one power processing stage, which can operate as step-down or step-up voltage, lower harmonic distortion in the line current and natural isolation. The converter work...
