This paper presents a single-phase boost inverter with the common ground operation. A switched inductor-based boost inverter is proposed. The primary feature of the proposed inverter topology is that it produces an ac output voltage higher than the dc input voltage. Traditional voltage source inverters have AC output voltage less than DC input voltage. The switches operate at a high frequency to use smaller passive components that improve system efficiency. The design requirements of components are presented for the inverter. The analysis of this inverter is performed through simulations in MATLAB/Simulink environment. The study is validated through a 1kW inverter at a DC input voltage of 72V and AC output voltage of 230V, achieving maximum efficiency of 97%.

The control of power electronics converters (PEC) is an integral part of the overall design. The cost and controlling capability of the controller are very critical selection criteria for economical PECs design. Recently a variety of cost-effective microcontroller development boards have been introduced with different capabilities not only restricted to power electronics applications. The theoretical and experimental understanding of these boards is key to finding the feasibility and utility for specific applications. It is essential to understand the PWM pulse generation capability with the desired range of frequency, duty ratio, and the number of available IOs for controlling the power electronics switches in PECs. This manuscript experimentally tests the low-cost microcontroller boards and interfaces with MATLAB/ Simulink environment for rapid prototyping PECs and to check the efficacy.

To sustain life in earth we need considerable amount of energy. For our body it is given by food we eat but we also need energy for machines and equipment for them to work. Since non-renewable source of energy is exhaustible in nature so nowadays we move towards renewable source of energy. One of the major sources of renewable energy is sun. Today we are using only a small amount of solar energy by using solar cells. These solar cells are placed at fixed position so amount is limited. To increase the amount of energy we receive we use solar tracker. Solar tracker is the device used to follow the sun. In this paper we deal with dual axis solar tracker with real time tracking technology. By this method we can increase the solar energy production up to 45%.

Surveillance based on computer vision is the need of the current era. Most of the existing surveillance cameras which are being used by the Security Services and Military Forces works on the sensor-based analysis of conditions, it activates a signal indicating the presence of some movable creature and cannot accurately differentiate between a hare, a deer or a human. The current surveillance methods show high accuracy in presence of daylight but fail miserably in low light conditions because these sensors equipped with normal cameras are not able to capture images with the same accuracy in such conditions. Hence to overcome this problem, we propose a network that is a combination of Human and Face Detection systems to distinguish between different entities and enhance the accuracy of the results. This model works well in extreme conditions such as low-light, blurred images, fog, haze or when most of the body or face is covered.

In this paper, a comparative analysis is done between two bi-directional DC-DC converters i.e. transformerless and with transformer. Traditional batteries are unidirectional and large in size but bi-directional DC-DC converter (BDC) interconnected between battery and 400V DC bus provides wide voltage gain ratios and facilitates power flow in buck mode (charging) and boost mode (discharging). Energy storage is required in isolated microgrid in order to save power during OFF-load period and to deliver when excess loads are connected; therefore it is necessary that battery must be bi-directional. This bi-directional battery has applications in nanogrid or microgrid for energy storage, electric heavy vehicles, uninterrupted power supply, etc. The two BDCs are modeled, simulated, controlled and operated in different modes using MATLAB/SIMULINK. The results of comparison using various criteria are discussed in this work.

In hybridization of energy sources with distinct voltage–current characteristics, power electronic converter plays crucial role for efficient and reliable energy diversification. In this paper nonisolated dual input converter is proposed for integration and diversification of energy from two different sources with distinct voltage–current characteristics. The proposed dual input converter (DIC) is proficient for energy diversification from two sources individually and concurrently with series and parallel combination of connected sources. The proposed topology can be operated in buck, buck-boost and boost modes of operation. It offers compact design, higher degree of reliability in operation, simplicity in control and flexibility in selection of input source voltage magnitude. Comprehensive analysis of the proposed converter and detailed comparison with existing literature has also been presented. The proposed concept has been simulated in MATLAB SIMULINK and validated experimentally using dSPACE 1103 real time digital signal controller.

This Solar Power has gained widespread attention by academia and government as an alternative cleaner source of energy. It is far more promising as compared to all other sources of energy. However, Solar Power has its own issues when it comes to installation. One of the major problems with solar power is dust settlement on solar panels. A number of approaches have been developed to solve this issue. However, either these approaches are very costly, inefficient or have a detrimental effect on the environment. This study systematically examines an indigenously developed Solar Panel Dust cleaning system and its impact on energy efficiency of the Solar Panel using a 1KW roof-top Solar Panel in an industrial town of India - Bhilai. The study also builds a GUI in MATLAB for prediction of energy reduction on a solar panel due to dust accumulation. Finally, this study presents a basic cost-benefit analysis to examine the return on investment in such a dust cleaning system.
