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...

This paper presents performance evaluation of an asymmetrical parameter type two-phase induction machine drive using two-phase three-leg voltage source converter (VSC) operating in motoring and generating modes. A system is simulated using MATLAB/SIMULINK. The proposed converter system includes a machine side converter using a three-leg VSC and a front end converter using a single-phase full br...

A novel integrated buck-flyback non isolated power factor (PF) correction (PFC) converter is proposed in this paper. This new converter is an inherent integration of a buck converter and a flyback converter, which operates in either flyback mode or buck mode according to whether the input voltage is lower or higher than the output voltage. In this way, the dead zones of ac input current in trad...

in this paper the maximum power point tracking (mppt) algorithms for wind energy systems arereviewed. as the amounts of power produced in wind power plants is changing due to theinstantaneous changing nature of the wind, it is desirable to determine the one optimal generatorspeed that ensures maximum energy yield. thus, it is important to include a controller that cantrack the maximum peak rega...

This paper introduces a novel Bi-directional DC-DC converter with artificial neural network controller (ANN).Bidirectional power flow is obtained by the same power components and provides a simple, efficient, and galvanically isolated converter. In the presence of DC mains the converter operates as buck converter and charges the battery. When the DC main fails, the converter operates as boost c...

A 15 bit Sigma-Delta ADC for a signal band of 40K Hz is designed in MATLAB Simulink and then implemented using Xilinx system generator tool. The second order SigmaDelta modulator is designed to work at a signal band of 40 KHz at an Oversampling ratio (OSR) of 128 with a sampling frequency of 10.24 MHz.

Today, design requirements are extending more and more from electronic (analogue and digital) to multidiscipline design. These current needs imply implementation of methodologies to make the CAD product reliable in order to improve time to market, study costs, reusability and reliability of the design process. This paper proposes a high level design approach applied for the characterization and...

Single-Stage transformerless AC/DC converter received much attention in the universal line application. Unlike the existing converters a new high step-down transformerless single-stage single-switch AC/DC converter is proposed. The topology integrates a buck-buck-boost converter with low intermediate bus and output voltage. The converter utilizes a buck converter as a PFC cell and buck-boost co...
