TL;DR: A detailed hardware design of the converter and MPPT method is carried out with the very good result shows that this design can effectively realize the actual practical Boost converter.
Abstract: This paper presents a detailed design of portable boost converter. The input is obtained by using photovoltaic (PV) system along with the maximum power point tracking algorithm (MPPT) to pull out maximum power. The boost converter is used to increase the fluctuating PV array voltage to high constant DC voltage. ATmega328 microcontroller is used to design the algorithm and able to track the PV voltage and current with the help of sensors and provides the appropriate pulse width modulation (PWM) signal to control the MOSFET in the boost converter. The main objective of this work is to implement perturb and observe (P&O) method as MPPT to control the boost converter. A detailed hardware design of the converter and MPPT method is carried out with the very good result shows that this design can effectively realize the actual practical Boost converter.

Modified Perturb and Observe Method are used to generate the duty cycle for the Step-up Converter. Level Shifted Pulse Width Modulation is used to generate the gate signal s for the Voltage Source Inverter. The overall design of the proposed system is simulated in Matlab/Simulink environment. The simulation results validate the feasibility of the proposed system.

Abstract: Sensor is an electronic module whose purpose is to measure the parameters of the system and send those details to the control station. Sensor plays an important role in many applications to ensure the successful operation of the system. The main objective of this paper is to summarize the application of sensors and its characteristic features in various stages of solar power generation system and also the implementation of voltage and current sensors in real time. To evaluate the performance of voltage and current sensor in real time the experimental setup of Boost Converter has been developed in the laboratory for Photovoltaic (PV) application by using Maximum Power Point Tracking (MPPT) techniques through the dSPACE DS1103 Rapid control prototype interface. It is envisioned that the information provided in this paper to serve as a valuable reference for future research in sensor application.

TL;DR: In this article, the perturb and observe (PO) algorithm is used in photovoltaic (PV) systems to maximize the PV array output power by tracking continuously the maximum power point (MPP) which depends on panels temperature and on irradiance conditions.
Abstract: Maximum power point tracking (MPPT) techniques are used in photovoltaic (PV) systems to maximize the PV array output power by tracking continuously the maximum power point (MPP) which depends on panels temperature and on irradiance conditions. The issue of MPPT has been addressed in different ways in the literature but, especially for low-cost implementations, the perturb and observe (PO moreover, it is well known that the P&O algorithm can be confused during those time intervals characterized by rapidly changing atmospheric conditions. In this paper it is shown that, in order to limit the negative effects associated to the above drawbacks, the P&O MPPT parameters must be customized to the dynamic behavior of the specific converter adopted. A theoretical analysis allowing the optimal choice of such parameters is also carried out. Results of experimental measurements are in agreement with the predictions of theoretical analysis.

TL;DR: In this paper, a buck-type DC/DC converter is used to maximize the photovoltaic array output power, irrespective of the temperature and irradiation conditions and of the load electrical characteristics.
Abstract: Maximum power point tracking (MPPT) is used in photovoltaic (PV) systems to maximize the photovoltaic array output power, irrespective of the temperature and irradiation conditions and of the load electrical characteristics. A new MPPT system has been developed, consisting of a buck-type DC/DC converter, which is controlled by a microcontroller-based unit. The main difference between the method used in the proposed MPPT system and other techniques used in the past is that the PV array output power is used to directly control the DC/DC converter, thus reducing the complexity of the system. The resulting system has high-efficiency, lower-cost and can be easily modified to handle more energy sources (e.g., wind-generators). The experimental results show that the use of the proposed MPPT control increases the PV output power by as much as 15% compared to the case where the DC/DC converter duty cycle is set such that the PV array produces the maximum power at 1 kW/m/sup 2/ and 25/spl deg/C.

TL;DR: In this article, a modified adaptive hill climbing (MAHC) MPPT method is introduced, which can be treated as an extension of the traditional hill climbing algorithm, and it can avoid tracking deviation and result in improved performance in both dynamic response and steady-state.
Abstract: Maximum power point tracking (MPPT) must usually be integrated with photovoltaic (PV) power systems so that the photovoltaic arrays are able to deliver maximum available power. In this paper, a modified adaptive hill climbing (MAHC) MPPT method is introduced. It can be treated as an extension of the traditional hill climbing algorithm. The simulation and experimental results show that the proposed MPPT control can avoid tracking deviation and result in improved performance in both dynamic response and steady-state.

TL;DR: In this article, an adaptive perturb and observe (P&O) method is proposed to track the maximum power point (MPPT) in photovoltaic (PV) systems.
Abstract: The optimisation of energy generation in a photovoltaic (PV) system is necessary to let the PV cells operate at the maximum power point (MPP) corresponding to the maximum efficiency. Since the MPP varies, based on the irradiation and cell temperature, appropriate algorithms must be utilised to track the MPP. This is known as maximum power point tracking (MPPT). Different MPPT algorithms, each with its own specific performance, have been proposed in the literature. A so-called perturb and observe (P&O) method is considered here. This method is widely diffused because of its low-cost and ease of implementation. When atmospheric conditions are constant or change slowly, the P&O method oscillates close to MPP. However, when these change rapidly, this method fails to track MPP and gives rise to a waste of part of the available energy. An adaptive P&O method is proposed in this study that has faster dynamics and improved stability compared to the traditional P&O. The MPPT algorithm was set up and validated by means of numerical simulations and experimental tests, confirming the effectiveness of the method.

TL;DR: This paper presents a maximum power point tracking approach for a photovoltaic system using the dividing rectangles algorithm, which is capable of searching for global maximum and possesses a fast tracking speed.
Abstract: This paper presents a maximum power point tracking approach for a photovoltaic system using the dividing rectangles algorithm. The new approach overcomes some weaknesses of the existing methods such as the perturb and observe method as it is capable of searching for global maximum. This is particularly important for a system that is partially shaded. To validate the performance of the proposed scheme, experimental studies have been conducted. The results have shown that the proposed approach is robust and possesses a fast tracking speed.
