abstract: Renewable energy sources and technologies are increasingly gaining popularity in developing countries as their increasing energy demand can be met by the unexplored potential of renewable energy. With help of decentralized system the power can be directly used at local load centers which will ease centralized grid. The Impedance Source Inverter (ZSI) has many unique advantages as compared to normal Voltage Source Inverter (VSI) and is suitable for both centralized and decentralized applications. This paper elaborates the distinguishing feature of ZSI which makes it suitable for isolated and grid integrated applications for a source whose nature is highly intermittent. Operating principle, steady state analysis, different carrier modulation techniques to control shoot through (ST) states are described. ZSI is able to maintain the constant load bus voltage when connected to a highly intermittent PV panel with help of suitable control technique. Its superiority in decentralized photovoltaic (PV) application is verified with help of MATLAB/Simulink environment. An insight of inter dependency of semiconductor device voltage stress, boosting factor (B) and modulation index (M) for sinusoidal pulsewidh modulation (SVPWM) control techniques is also presented.

abstract: This paper discusses the performance of Maximum Boost Control Z Source Inverter (MBC ZSI) on the application of Induction Motor Drives with varying loads. The proposed system is able to achieve a steady speed of 1198 Rpm in an average time of 0.5 s with a variable motor load. To validate the performance of the proposed system, a comparison is made with the SPWM VSI inverter system. The results of the comparison found that MBC ZSI requires a faster time to reach a steady speed with an average of 0.26 s even though the load on the motor changes.

abstract: The paper focuses on the implementation of selective harmonic eliminated (SHE) PWM applied to the three phase voltage source inverter (VSI) to supply synchronous machine with permanent magnets. Theoretical basis of the obtaining of the three phase VSI switching angles, that provide given spectrum of the output voltage is expounded. Values of the switching angles are derived by the Newton Raphson iterative method. Mathematical model of permanent magnet synchronous motor drive system with VSI is designed. Simulation and comparison of the sinusoidal pulse width modulation (SPWM) and SHE PWM algorithms of power VSI is present.

abstract: Abstract In this paper we address the problem of consensus in hardware interconnected networks. As an example of such, we focus on three phase AC microgrids with Voltage Source Inverters (VSI) as generation units and the consensus control objectives of active power sharing and frequency synchronization. By distinguishing between the interconnected control plant, the control objectives, and the feedback controller, we analytically study a non linear model of the power flow within the microgrid through a robust linear approximation. From here we suggest a Linear Matrix Inequality (LMI) based methodology to verify that the proposed control strategy makes the network reach the consensus objectives. The theoretical analysis is complemented with a simulation study of an arbitrary microgrid.

abstract: This paper investigates the power losses for two different IGBT technologies (nonpunch through and punch through) for use in PWM VSI inverters in order to choose the right device technology for a given application. A loss model of the inverter is developed based on experimental determination of the power losses. The loss model is used on two different modulation strategies which are a sine wave with a third harmonic added and a 60/spl deg/ PWM modulation where only two inverter legs are active at the same time. The two IGBT technologies are characterized on an advanced measurement system which is described. The total power losses in the inverter are estimated by simulation at different conditions and it is concluded that the nonpunch through (NPT) technology is most useful for higher switching frequencies, while the punch through (PT) technology is especially useful at lower switching frequencies and high load currents. It is also concluded that the 60/spl deg/ PWM modulation has the lowest power losses and the power losses are almost independent of phase angle cos(/spl phi/ for normal motor operation.

abstract: A method for minimisation of current harmonics spectrum for asynchronous traction motor fed from three level neutral point clamped voltage source inverter is described in this study. A selective harmonic elimination and mitigation based algorithm using particle swarm optimisation has been utilised. Since the load is an induction motor suitable for traction application, a modified objective function with constraint of individual current harmonics has been proposed in this study to obtain improved harmonic elimination and control with low switching frequency. The proposed method has been compared with conventional technique considering only torque spectrum as objective function. Moreover, a suitable formulation for loss calculation has been proposed to optimise both the motor losses and torque harmonics. Suitable simulations along with experiments are performed with a practical induction motor of cage type to justify the proposed method.

abstract: The current source inverter (CSI) is a power electronics topology that allows for the realization of variable speed drives (VSD) Compared to the most common voltage source inverter (VSI) which can be directly connected to a voltage source, the CSI needs a prestage to generate a constant current bus. This article therefore seeks to challenge this "accepted" consideration that a CSI always needs this precircuit and seeks to remove this circuit by proposing an innovative $i_{dc} current control scheme. The proposed scheme is applied to a single stage motor drive driven by a CSI converter. It is shown how implementing this control scheme removes the need for the front end stage, thus removing an unnecessary converter and optimizing the efficiency at the same time. The CSI state space equations are presented and the developed models are verified using simulations. Stability analysis of small signal model is considered through Nyquist criterion with the robustness in presence of variations of the most important system parameters. Experimental results driving a permanent magnet synchronous machine (PMSM) are shown confirming the validity of the proposed control, potentially paving the way to a larger adoption of the CSI topologies for motor drive applications.

abstract: In this paper a three phase voltage source inverter (VSI) has been simulated with controller circuit that can be used in future for hardware implementation using dSPACE 1104 controller in photovoltaic application. The dSPACE controller can be used, as it can link the MATLAB Simulink model directly into a real time operating prototype. The switching of IGBTs will be controlled by generating sinusoidal pulse width modulation (SPWM) signals with proportional integral (PI) controller circuit and parks transformation. The three phase inverter ac output voltage will be stabilized with the help of controller circuit attached to it in simulation model. Here DC voltage source is taken as the photovoltaic generator that supplying power to the three phase inverter. With this model the simulation output is showing a result of 2.83% of total harmonic distortion and supports that the controller circuit used is improving inverter ac voltage output to a great extent. This control system can be transformed into a prototype model with the dSPACE controller board as suggested in this paper.

abstract: In this paper, an optimal voltage control structure for Voltage Source Inverter (VSI) in series with LC filter for Medium Voltage DC Shipboard Power System (MVDC SPS) applications is proposed. The objective of the proposed method is to design a closed loop controller that makes the output of the system optimally track a given desired signal and reject a given disturbance. Therefore, it is called Linear Quadratic Tracking (LQT) which is considered as a modified form of the Linear Quadratic Regulation (LQR) Computer simulation is used to validate the performance of the proposed control scheme under different scenarios.
