“…The electrical power generated by a solar PV panel mainly depends on the operating conditions, solar irradiation in w/m 2 , temperature in degree Celsius, number of cells, short circuit current (I sc ), etc. In this proposed system, in order to attain the maximum power from the PV panel, the P&O MPPT algorithm has been used [19][20][21][22]. The voltage and current relations for a single diode model array can be expressed as…”

Application of multilevel inverters has been an active research area in recent years due to their growing importance in various diversified electrical utilities. A three-phase inverter with a single DC source employing a three-phase transformer for a grid-connected photovoltaic (PV) system controlled using the modified space vector pulse width modulation technique (MSVPWM) for fifteen switches is presented in this paper. An MSVPWM technique is implemented through a field-programmable gate array (FPGA) and generates high quality gate pulses to the switches in the inverter. The main advantages of the proposed inverter topology are reduced number of power switches, transformers and minimum total harmonic distortion (THD). The perturb and observe maximum power point algorithm is used to obtain the maximum power from the PV panel at all climatic conditions. The performance of the proposed system is validated through MATLAB/Simulink as well as an FPGA-based prototype model.

Abstract:Recent development of the Internet of Things (IoT) and Smart Things provides an opportunity for the informationization for the automotive industry. This article describes Obstacle Detection and Alert System (ODAS) both incorporated as a single system for the obstacles such as speed breakers, barricades on the road using Internet of Things. Obstacle detection system uses in-built algorithm to detect an obstacle on the road using minimal vehicle parameters such as vehicle speed, steering angle. Obstacles locations thus marked by the detection system are stored locally and uploaded to cloud from time-to-time. Cloud server processes data from different vehicles and finalizes that there is a real obstacle at the particular location based on its own algorithm. Obstacles locations thus confirmed by the cloud server are downloaded to obstacle alert system from time-to-time, which alerts the driver about the obstacle on the road when the driver is nearing the location of the obstacle. This system also provides option to see obstacles location super-imposed on google maps so that user can plan his efficient route in advance. Existing systems only have road sign indications for obstacles such as speed breakers, barricades which the driver might not notice during driving, especially at night times. Existing google maps data do not have option to find road obstacles such as speed breakers, barricades information on it. The system aims to overcome these short-comings by a dedicated system which provides audible and visual alert about road obstacles.

“…If we have to reduce life cycle costs of a building from construction to maintenance, it is very effective to monitor structural health of a building and application on power electronics [7][8][9][10][11]. A damage identification system based on vibration measurements is effective for damage detection of whole structures or the story of a structure but it is not effective for damage detection of a specific portion of a building such as its structural members.…”
