The paper presents the controller structure of high performance, double-stage three phase grid connected solar photovoltaic (PV) system with maximum power point tracking (MPPT). In, the proposed configuration, the solar energy, after MPPT tracking, is finally channeled into a three phase AC grid by first boosting up the DC voltage level and then converting the boosted DC voltage into three-phase AC by means of a grid-tie inverter. The control of the pulse-width modulated (PWM) three phase inverter is realized similar in line with field-oriented control of electrical AC machines, using dq transformation along with feed-forward compensation. The practical and effective design steps are clearly explained to find out the controller parameters. The displacement factor at grid end is maintained unity and distortion of the current, fed into the grid, is restricted as per the IEEE-1547 standard. The analytical findings and simulation results are well agreeing.

A hybrid technique is suggested for optimal management of the Micro grid (MG) system in this paper. The suggested technique is the mixture of Cuckoo Search (CS) and Bat algorithm. Now, the multi objective function is employed to get the optimal operation and management of MG. Using the fuel cost with the operating and maintenance cost of the MG sources like Fuel Cell (FC), Micro Turbine (MT) and Diesel Generator (DG) the multi-objective function is improved. The suggested technique optimizes the MG source combinations with cheap cost, while pleasing the load demand. The suggested technique is used to determine the optimal combination of the MG source and their minimum costs, in order to please the load demand. In the MATLAB/SIMULINK platform the suggested method is executed and the performance assessment is performed by comparing the suggested technique with the presented techniques. The outcome, attained exposes the advantage of the suggested method and it is very much improved than that of other techniques.

Z-Source inverters can overcome some of the limitations, inherent in traditional Voltage Source and Current Source Inverters and can provide boosted outputs. Most of the literature on Z-source inverters deals with 3-phase or 1-phase bridge inverters. This paper proposes a Single-Phase Z-Source Push-Pull Inverter topology. This scheme has several advantages compared to basic Z-source full-bridge inverter. Simulation result of the converter is presented as the proof of the concept.

The paper presents on the improved soft switching buck converter in terms of the zero voltage switching (ZVS) and zero current switching (ZCS) which reduces mainly switching power losses of the main semiconductor compared with the hard switching skill over a wide range of the load variations. The soft switching with zero current turns on so the lagging leg of the main switch is achieved ZVS during turned off time to improve the performance of the converter. Thus, it is far better to use power MOSFET as a very high switching frequency power device due to the natural voltage fed nature of the buck converters so overall efficiency be significant with the proper designing of the power inductor, selection of the active and passive power devices and discontinuous conduction mode (DCM) of the operation.

This paper deals with the identification of a faulty load bus, in a multi-bus power system, monitoring the inter-harmonic and sub-synchronous inter-harmonic operating point in P-δ plane, depending on passivity model based Gauss-Seidal iteration technique. In this analysis, real power, load angle and bus voltage have been calculated and the shifting of the various operating points in the inter-harmonic and sub-synchronous inter-harmonic P-δ curves have been assessed, for different feeders. The technique has been implemented in IEEE 30 bus system. Considerable change has been seen for fundamental and sub-synchronous inter-harmonic operating points in P-δ plane.

The paper presents a recursive method using Taylor series to solve the states of time invariant control systems with and without delay. First of all, the Taylor series, both first and second order, are utilized to solve the state equation of a linear time invariant (LTI) system recursively. Subsequently, a recursive algorithm is proposed for solving an LTI system with delay. The states of the system solved using Taylor series are compared with exact solutions. The approach is much simpler than other established methods, and also, it proves to be reasonably accurate. The recursive algorithm presented avoids the use of any delay matrices. As expected, for same number of recursion steps, the second order Taylor series solution proves to be more efficient than the first order Taylor series approach. Examples are treated and the results obtained are presented via tables and graphs.

A simple approach based on input to state stability (ISS) criterion for input tracking and stabilisation of a Lipschitz nonlinear system is being proposed. The controller design is carried out in a linear matrix inequality (LMI) framework. The resulting controller, if feasible, tracks the input reference signal and also provides stability to the system. The designed closed loop system is robust against parametric norm bound uncertainty.

Flash type analog to digital converters (ADCs) have the highest speed amongst all the available ADCs because of their parallel architecture. The comparator outputs in a flash ADC are in the so-called `thermometer code' form. Because of device mismatch, clock jitter, offset voltage and metastability problems prevalent in a flash ADC, it suffers from bubble or sparkle error problem. This thus leads to an erroneous output code with consequent disastrous performance. Several researchers have attempted to overcome the bubble error problem with various bubble error correction (BEC) schemes but with limited success. An attempt has been made in this paper to correct the bubble error - the degree of correction vary from the first order to any higher order. Simulations have been carried out on the proposed circuit - both for first and second orders. It has been established that it requires lesser number of transistors and thus would consume less power.
