This paper presents concept of single phase matrix converter. Single phase matrix converter (SPMC) performs a function such as frequency changer, rectifier, inverter; chopper. This reduces the need for new converter hardware. Pulse width modulation (SPWM) techniques are used to calculate the switch duty ratio to synthesis the output. The simulation of converter is carried out in MATLAB/SIMULINK...

Dynamic equations describing the buck converter are derived and linear peak current mode controller is designed. The buck converter, the voltage mode and current mode controller are modeled and are evaluated by computer simulations. The proposed technique has the advantages...

An averaged model of a coupled-inductor boost converter using the piecewise complementarity model of the converter under sliding motions is obtained. The model takes into account the idealized voltagecurrent characteristic of passive switches (diodes) present in the converter. Because of its lower complexity, the averaged model is more suitable for control design purposes as compared with the l...

This Paper presents the application of Single Phase Matrix converter as a Cycloconverter and Cycloinverter. Sinusoidal Pulse Width Modulation (SPWM) technique is used to generate control pulses for the Matrix Converter switches to produce output. The switching sequences for the Matrix Converter to operate as Cycloconverter and Cycloinverter are presented and evaluated using MATLAB/ Simulink. Th...

This paper presents a simple input-constrained current controller for a DC/DC boost converter with stability analysis that considers the nonlinearity of the converter model. The proposed controller is designed to satisfy the inherent input constraints of the converter under a physically reasonable assumption, which is the first contribution of this paper. The second contribution is providing a ...

A constant voltage regulator, to supply constant power loads, is realized using a Switched-capacitor converter. Exhaustive studies have been carried out to find the suitability of available control schemes and finally one control scheme investigated with (i) operation of the converter at different crossover frequencies (ii) operation of the converter at different phase Margins. Various operatin...

Abstract: A stand-alone multi-microgrid (MMG) system can be formed by connecting multiple stand-alone microgrids (MGs). In the stand-alone MMG system where the frequencies of each MG system are different, a back-to-back (BTB) converter can be used for interconnecting the adjacent MG system. The frequency control performance of the MMG system can be improved by designing the suitable controller ...

Single phase unified power quality conditioner (UPQC) consists of series and shunt active power filter (APF) with common dccapacitor. Series converter acts as voltage source converter and shunt converter acts as current source converter. Use of non-linear loads results in voltage and current harmonics. These harmonics can be eliminated by using single phase UPQC. So that, which also improves th...

Design-oriented analysis of switching converters must take into account how disturbances and variations in the input and control signals affect the optimum performance of these converters. Sate-space averaging of a nonideal boost converter is presented in this paper. DC state and small signal AC state modeling of the converter was derived. Determination of line-to-output transfer function, whic...

Abstract: Fast control DC-link voltage is the key to enhance Low-Voltage Ride-Through (LVRT) for the Permanent Magnet Synchronous Generator (PMSG). When grid voltage dips deeply, by the constraint of the capacity of the grid-side converter and reactive power support by the grid-code required, the active power capacity of the grid-side converter will be reduced. Therefore, it cannot stabilize th...
