This paper explains the design and implementation of perturb and observe Maximum Power Point Tracking algorithm combined with the Closed Loop Digital PI control algorithm to generate the Digital Pulse Width Modulation using Xilinx Spartan 3A DSP Field Programmable Gate Array for regulating the load voltage of DC-DC buck converter. And also concentrates on the methods for generation of DPWM techniques say Delay line based Digital Pulse Width Modulation and Hybrid based Digital Pulse Width Modulation with the 210 bit resolution. All the algorithms are developed by VHSIC Hardware Description Language coding and are implemented using Xilinx ISE 12.1 tool. The hardware results validate the satisfactory voltage regulation of PV system under continuous changing weather condition. The Hybrid based Digital Pulse Width Modulation seems to have better time transient response than the Delay line based Digital Pulse Width Modulation. (c) 2017 Elsevier Ltd. All rights reserved.

This paper deals with the detailed design of induction motor used for PV (photovoltaic) array fed water pumping application. The motor is designed for efficiency improvement by decreasing its losses. The mechanical sensorless system adopts stator voltage and current based speed estimation using stator voltages and stator currents. Moreover, artificial neural network (ANN) based direct torque control (DTC) is used here for speed control of the drive. The proposed design with improved efficiency induction motor drive operated water pumping system does not use any mechanical sensor. Therefore, overall system is designed to improve efficiency with a reduction in cost. and complexity with simultaneous assurance of optimum power utilization of PV array. A detailed discussion on various factors affecting the efficiency of the motor is carried out, which is used to improve the behavior of the IMD for water pumping. The designed motor is tested on developed prototype in the laboratory and its suitability is judged through various results under steady state and dynamic conditions of insolation variations.

This chapter describes the variable speed stand-alone wind power supply system that incorporates permanent magnet synchronous generator, three-phase diode rectifier, and improved dc-dc boost converter with resistive load. Improved dc-dc boost converter controls to concentrate the most extreme power from the accessible wind. In the wind generation system, the power converter efficiency is one of the important considerations realizing the system performance. In those systems, dc-dc step-up converter is broadly utilized for high-conversion system. Considering the converter's expense and efficiency, this chapter mostly concentrates on the outline of an enhanced topology of the boost converter received for high-power stand-alone wind power system. It describes the perturbation and observation maximum power point tracking algorithm. The MPPT algorithm in addition to the dc-dc step-up converter is simulated by MATLAB/Simulink software. The outcomes demonstrate that the dc-dc converter topology can understand the most extreme power point tracking control of the wind turbine.

To make full use of the maximum output power of automobile exhaust thermoelectric generator (AETEG) based on Bi2Te3 thermoelectric modules (TEMs), taking into account the advantages and disadvantages of existing maximum power point tracking methods, and according to the output characteristics of TEMs, a hybrid maximum power point tracking method combining perturb and observe (P&O) algorithm, quadratic interpolation and constant voltage tracking method was put forward in this paper. Firstly, it searched the maximum power point with P&O algorithms and a quadratic interpolation method, then, it forced the AETEG to work at its maximum power point with constant voltage tracking. A synchronous buck converter and controller were implemented in the electric bus of the AETEG applied in a military sports utility vehicle, and the whole system was modeled and simulated with a MATLAB/Simulink environment. Simulation results demonstrate that the maximum output power of the AETEG based on the proposed hybrid method is increased by about 3.0% and 3.7% compared with that using only the P&O algorithm and the quadratic interpolation method, respectively. The shorter tracking time is only 1.4 s, which is reduced by half compared with that of the P&O algorithm and quadratic interpolation method, respectively. The experimental results demonstrate that the tracked maximum power is approximately equal to the real value using the proposed hybrid method,and it can preferentially deal with the voltage fluctuation of the AETEG with only P&O algorithm, and resolve the issue that its working point can barely be adjusted only with constant voltage tracking when the operation conditions change.

Inage of Green energy revolution, solar energy comes into prominence in aerospace for providing fuel requirements for mini Unmanned Air Vehicle (mUAV). Conversion of this abundant solar energy into useable form will reduce the dependence on battery which is used in mUAV, while increasing the energy on board. In this work, an attempt has been made to model and simulate a photovoltaic cell with MPPT module and DC-DC converter. Photo voltaic cell works at highest efficiency when it is operating at its maximum power point. A DC-DC converter is used between the solar cell and the load as an interface. A boost converter is implemented as it serves the purpose of operating over the entire range of PV cell. The duty cycle is varied so that the impedance matching between the cell output and the load is achieved, by tracking the maximum power point of the cell. The idea is to ensure maximum performance of the setup, irrespective of the changes in physical conditions. Analysis is carried out with and without MPPT module to calculate efficiency. PV cell based renewable energy is more efficient with MPPT module as compared to without MPPT module.

This paper presents an extensive study of photovoltaic system using three non-isolated DC-DC converters, to extract maximum power. Firstly, a comparative study on different methods of MPPT is carried out and from this comparative analysis it was observed that the perturb and observe algorithm provides better results.

Based on simulation results, and further as a novel contribution in this work, a prototype of MPPT based PV system is designed using perturb and observe algorithm and Buck-Boost type of DC-DC Converter. Finally the experimental results are demonstrated.

This paper presents the maximum power point tracking for stand-alone photovoltaic system using current based technique. This method mitigates the disadvantage of conventional perturb and observe (P&O) technique in term of both transient and steady-state responses. The simulation results show that the proposed current based MPPT technique can provide the maximum power point value closed to the corresponding maximum power of photovoltaic for each irradiance. Both transient and steady state responses are better than those of conventional P&O technique.

In the last decade, the use of renewable energy resources instead of fossil fuels pollutants has increased exponentially. Photovoltaic energy generation is ever more important as a renew able resource since it does not cause in fuel costs, pollution, maintenance, and emitting noise compared to other renew able resources as more accessibility of solar irradiation. In this paper, The Maximum Power Point Tracking (MPPT) controller for boost converter based on perturb and observe control is developed and compared to conventional tracking algorithm Incremental Conductance. The different steps of the design of these controllers are presented together with its simulation. The whole system is simulated under standard climatic conditions (1000 W/m2, 250C) in MATLAB and the irradiance is varied from 600 W/m2 to 900 W/m2. Results of this simulation shown that the system with MPPT using P&O controller increase the efficiency of energy production from PV.

This paper focuses on wireless power transfer based on Witricity technology, specifically wireless battery charger application for electric vehicle. In order to reach efficient power transfer, a principle of coupling magnetic resonance at high frequency is used. However, in high range frequency, several losses may offer such as peak power, switching losses as well as reducing the size of the required battery capacity. In order to avoid the battery's damage, perturb and observe maximum power point tracking algorithm connected with photovoltaic panel is performed. The main objective of this contribution based on proposing a self-correction algorithm to adjust misalignment between primary and secondary coils caused by a random parking of the electric vehicle and to produce suitable input power battery at important frequency level.
