This paper describes the direct torque and flux control strategy for an induction motor with open-end stator winding fed by a matrix converter at each end of its terminal. Use of the matrix converters instead of the conventional power converters eliminates the DC-link in the AC-DC-AC converter. Triggering the matrix converter using the rotating space vectors eliminates the common mode voltage at the machine terminals. The input-side power factor is also controlled by using the rotating vectors. The simulation is carried out in Simulink®/MATLAB® and the results show that the common mode voltage is eliminated while maintaining input power factor at unity.

This paper evaluates an isolated system using a character of triangle function (CTF) based control methodology for control and improved power quality. The hybrid-isolated system consists of a solar photovoltaic (SPV) array, diesel driven permanent magnet synchronous generator (PMSG) and a battery energy storage system (BESS). The configuration of the controller is simple and it is employed for the estimation of the source reference currents. The essential objective of a four-leg voltage source converter (VSC) is to provide voltage control, load balancing, neutral current compensation and harmonics elimination while feeding three phase four wire loads. The performance of the system with proposed control strategy has been estimated by modelling the system in Matlab with Simulink and SPS (Sim-Power System) toolboxes and authenticated through simulation results.

Power quality is a hot topic of concern for both suppliers and consumers. The increased use of non-linear loads like adjustable speed drives also deteriorates the power quality levels. Therefore, greater emphasis is now being given to the study, evaluation and improvement of power quality especially in power distribution network. In this paper, the application of Unified Power Quality Conditioner (UPQC) with PI controller to improve the power quality in a distribution network with Direct Torque Control (DTC) induction motor drive is investigated. The Simulink model and results of the test system are presented to draw the conclusions.

In system reliability analysis component importance plays major role for prioritizing the components in the system to improve the reliability, risk and maintenance planning. Maintenance of all the risky equipments is necessary to ensure successful operation of any system. Different importance measures are available to compute the rank of the component for improving the system reliability and maintenance planning. In this paper a set of seven existing importance measures and a non parametric ranking tool i.e Copeland Score (CS) method have been extended to analyze reliability improvement and component maintenance priority of the system.

This paper proposes the mathematical modeling of Photovoltaic (PV) module using single diode model and use it to study the performance of PV array under partial shading condition. Partial shading is one of the major causes of reducing energy output in solar PV array. Due to partial shading, PV characteristics get more complex. In order to extract maximum power under shading condition, its performance has to be studies. In this paper, Matlab based mathematical model is used to study the performance of Perturbation & Observation (PO) based Maximum Power Point Tracker (MPPT) controller under partial shading condition. Further, ecosense Insight Solar PV Training kit is used to justify the mathematical model.

A novel hybrid eighteen-level inverter topology for open-end winding induction motor (IM) is presented in this paper. In the proposed topology one end of the open-end IM is fed by conventional two-level inverter, while other end is connected to a nine-level cascade H-bridge (CHB) inverter. The combined effect of these two inverters generates eighteen-level in the phase voltage of open-end winding IM. The two-level inverter with higher DC link voltage has lower switching frequency and thereby reduces the switching losses. In addition to that, the proposed topology requires less number of components as compared to conventional multilevel inverter (MLI) topology. An interesting feature of the proposed topology is that, it can operate in nine-level mode by connecting the motor winding in star in case of failure of two-level inverter. Similarly if the fault occurs in CHB inverter the proposed inverter can operate in two-level mode. Thus the reliability of the system is improved. Exhaustive simulation study is carried out to evaluate the performance of proposed inverter for the entire modulation range and results are presented.

The paper appropriately presents to popularize a sizeable copy of green power from the solar energy carried out by the flyback converters. The copy and paste of the free energy is married by a straight forward elemental optimization technique at which the conventional energy is shut down during the on grid to save power. The renewable energy is exclusively copied in backup systems and pasted for the off grid utilization or hurling over surplus power at the nearby grids to crack the monopole business of the power utilities. Last but not least, substantial solar power agriculture is accomplished by copy and paste modes of the smart operations.

To extract maximum available power from the PV system many maximum power point tracking (MPPT) algorithms with DC-DC converter have been proposed in the literature. However, due to change in load or environmental conditions, the output voltage from the DC-DC converter varies. The variable output voltages are not suitable for many applications requiring constant voltage. To overcome this difficultly, a cascaded DC-DC converter with battery storage system for standalone application is proposed in this paper. The proposed system comprises of a PV system connected with a boost DC-DC converter to deliver the available maximum power to the DC bus. A Single-ended primary inductor converter (SEPIC) is connected to the DC bus to provide regulated DC voltage to the load. A battery with charge controller is connected to the DC bus to improve the reliability of the system. The efficacy of the proposed topology is verified through the experimental studies pursued on a prototype PV connected converter system developed in the laboratory. Robustness studies with regard to variation in environmental parameters such as solar insolation and load variation were made. MPPT and voltage regulation algorithms were implemented in LABVIEW platform using data acquisition boards.

Power produced from the Renewable Energy Sources (RES) is directly feeding to the electric grid via Power Electronic Circuits (PEC). Grid connected solar Photovoltaic (PV) system requires a high quality of grid monitoring techniques in order to detect the phase angle, voltage magnitude and frequency and also to meet standard specifications in terms of achieving power quality and safety. Various techniques are used to detect phase angle, amplitude and frequency of the grid connected solar PV system. This paper proposes a review of important voltage monitoring techniques for single phase grid connected solar PV system and it also proposes a design of Adaptive Notch Phase Lock Loop (ANPLL) circuit for single phase grid connected solar PV system under both ideal and non-ideal grid conditions. Here the Loop Filter (LF) of the PLL circuit is a Proportional Integral Derivative (PID) type and the proposed PLL circuit is implemented using Matlab/Simulink platform and simulation results are obtained for both ideal and non-ideal grid conditions.
