Essays on Inverter

Solar energy harnessing through the use of solar panels installed in small homes presents better alternative to the hydroelectric provided through the national grid. While the use of solar panels may provide several advantages over the use of hydroelectricity, its usage presents several pitfalls to the user. It is imperative to investigate and outline the possible costs and advantages associated with the use of solar panels as a source of harnessing solar energy before installation is started. In most cases, the decisions concerning the installation of solar panels as the primary source of electricity are normally based on the ...

at Rex Hill Winery

Management of Rex Hill Winery has been highly concerned about climate change. They have heard about the Solar Sprint campaign to go solar now before the federal tax credit expires at the end of 2016. They also knew about the other incentives available on installation of solar electrical systems. Considering environmental benefits, they desired to install a PV solar panel system at their property. However, they wished to take a final decision on the project based on a feasibility study. As Rex Hill’s consultant, I have been entrusted the job of preparation of a ...

Introduction

Power quality is an essential factor as far as performance of the electrical machines and equipment are concerned. Quality plays an integral role in ensuring reliability and satisfactory service by improving the transmission and distribution of electric power. In order to serve a huge section of the world with electrical power, quality is paramount in order to reduce losses during transmission and distribution. IEEE defines power quality as the deviation of current and voltage from the ideal to the actual realization. It factors in the concept of ensuring high standard powering and grounding of the electrical equipment for the ...

Abstract

Permanent magnet synchronous motors (PMSM) are a type of motors that have permanent magnets mounted on the rotors instead of the rotor windings. This particular design gives the motor a few advantages over ordinary induction synchronous motors. The magnets attached to the rotor do not require excitation, which reduces the power consumption in PMSM. This gives the motor high operational efficiency and reduces the motor active diameter. PMSM are therefore associated with applications that require high torque but have limited operation space. The permanent magnets suffer from flux leakage and are therefore aligned in a pattern that minimizes flux ...

Re: extended definition of solar power and nuclear power

Purpose This memo is an extended definition of solar power and nuclear power as sources of energy. Introduction Solar power is energy from the sun. This energy is harnessed by collecting sunlight and converting it to electricity (Winter et al. 4). The cells found in the solar panels make this conversion possible. The conversion of sunlight to electricity can either be done indirectly by the use of a concentrated solar panel or directly by use of the photovoltaic cell. Nuclear power, on the other hand, utilizes nuclear reactions to produce nuclear energy (Murray 495). This energy is found in ...

Introduction

Numerous electrical applications require an inverter, which converts Direct Current (DC) to Alternating Current (AC) power. Some of these applications require the stepping down of voltage levels when realizing this conversion, which signifies that the input DC power is greater than the AC power. Conversely, certain applications require the opposite: to step up voltage when performing the power conversion, which means that the input DC power is lower than the AC power. These requirements can be met through the use of Voltage Source Inverters and Current Source Inverters, respectively. However, some particular applications require to step down voltage for ...

Solving Social Problems: Solar Energy in Rural India

The developing world grapples with the lack of access to electricity. Third world countries have poor electrical infrastructure which is still in the nascent stages of development. As a result, majority of people, especially those living in rural areas, have no access to electricity. The reach of the electrical grid in countries is limited to towns, and the poor who have access to electrical power supply suffer frequent and prolonged power blackouts. As a result, people in such countries result to unclean and unhealthy means of lighting, such as kerosene and diesel generators. The kerosene lamps cause respiratory problems ...

Introduction

Solar power is a renewable source of energy that is effective in reducing the carbon footprint. Solar power is a perfect substitute for hydropower and the use of engines that run on petroleum products and steam (Benduhn, 18). This technology relies on the use of certain materials to capture and harness the sun’s energy into electric energy. Solar power generation employs environmental friendly means. The power generated can be converted into Alternating Current (AC) and used to run operations that would normally use hydropower and petroleum engines. As such, solar power generation and usage are energy-efficient and efficient in the ...

The harnessing of solar energy is basically the collection of radiant light and heat from the sun. The radiant light and heat that is harnessed is put to use using different technologies and is in the end stored for future use. The only way this energy can be stored is through the use of thermal mass systems. These systems store energy in the form of heat for seasonal or daily durations. Thermal storage takes the form of materials with a high specific heat capacity. Some materials such as Glauber’s salt and paraffin wax are relatively cheap and available ...

1. Abstract

The proposal aims at to giving a solution to the problem of low power output by designing a power generation system that maximizes power output by mounting the turbine on a D.C generator with a suitable coupling. This generator is then connected to the water pipe. The turbine is designed to generate electricity by converting kinetic energy from water flows to electric energy. The use of this technology proves sustainable as it works under minimum maintenance. In this proposal is included the conceptual approach, results ad conclusions arrived at validating the significance of conducting this research. In include but not limited to the ...
