An inverter or power inverter is an electronic circuitry that changes direct current DC to alternating current AC. Direct current is a type of current that flows in only one direction. Direct current DC is usually gotten from battery cells, solar panels, household generations etc. Alternating current is one in which current direction changes with respect to time, i.
In this case there is no fix polarity for the terminals of the power supply. This type of current is usually gotten from, public power supply distribution companies, industrial generators etc. Alternating current graph could take the form of sine wave, square wave, triangular wave, modified square wave etc. These graphs are shown in fig. The power supplied by industrial generator and public distribution companies is usually pure sine wave.
But commercial inverters could give output ranging from square wave, modified square wave to pure sine wave.
Although pure sine wave is most preferable for electrical equipments, it is usually costly because of the technology involved.
The modified square wave is predominate in house hold inverters. This modified sine wave is manageable for electoral equipment compared of square wave.
The basic difference between an AC and a DC source is that, while an AC alternate its current direction or polarity, a DC has fixed current direction and polarity.
The major work of an inverter therefore is to alternate the polarity of the DC power supply terminals. The circuit consists of a centre tapped step-up transformer, a battery and a switch. This arrangement gives out a square wave output. The switching system could be mechanical or electrical. Transistors of different power ratings depending on the power rating of the inverter can be used as switch for the circuits. Figure 1. The battery supplies power to the driver A.
This causes its blades to rotate. The belt transmits this rotary motion to driver B. The rotational motion of driver B brings about and alternating current at the terminals of driver B.
This alternating current is fed into the power amplifier. While the battery supplies the power voltage and currentthe AC current from the driver B causes it to oscillate.
The output at the power amplifier is fed into the step-up power transformer which steps up the voltage from 12 volt to volts. Modern inverters are mere development of these basic inverter circuit. As technology improved, vacuum tubes and gas filled tubes were used as switches for inverter circuit. Literature review and design of the inverter : Literatures will be reviewed to obtain the working principles and circuit diagram after which a design will be made to ascertain the rating and parameters of the different components involved in the inverter.

Chat with us!Inverters are widely used in the domestic as well as industrial environments to serve as second line of source in case of power cut form the electricity utility grids. However, due to low capacity of the battery the inverter dies out with the use of heavy load appliances. This project is designed in such a way that it overcomes this limitation by the use of solar energy.
This inverter generates up to V AC with the help of driver circuitry and a heavy load transformer. This battery gets charged from two sources, first being the mains power supply itself. If the mains power supply is available, the relay switches to the connection using mains power supply to supply to the load. This power supply also charges the battery for using it as back up the next time there is power outage. The use of solar panel to charge the battery gives an additional advantage of surplus power in case the power outage of mains is prolonging.

In a typical solar energy-harvesting system, multiple solar panels are connected in parallel to a single inverter that converts the variable DC output of multiple PV cells into a clean sinusoidal Hz voltage source. The performance of the entire solar PV system is dictated by the performance of the weakest solar panel. Therefore, power production is negatively affected by non uniformity of solar panels, sunlight variations or partial shading due to clouds, trees, dust on the panel.
DC such as V is distributed in the system and has the potential to trigger a high intensity arc which can cause fire. This is a major issue for installing a central inverter based solar power system on the roof of a commercial building. So Central inverters are not safe for the residential application. Equipping each panel with its own micro-inverter allows the system to accommodate its changing load and atmospheric condition, which provides optimal conversion efficiency for both the individual panels and the entire system.

One such alternative is solar energy. Solar energy is quite simply the energy produced directly by the sun and collected elsewhere, normally the Earth. The sun creates its energy through a thermonuclear process that converts about ,tons of hydrogen to helium every second.
The process creates heat and electromagnetic radiation. The heat remains in the sun and is instrumental in maintaining the thermonuclear reaction. The electromagnetic radiation including visible light, infra-red light, and ultra-violet radiation streams out into space in all directions.
Only a very small fraction of the total radiation produced reaches the Earth. The radiation that does reach the Earth is the indirect source of nearly every type of energy used today. The exceptions are geothermal energy, and nuclear fission and fusion.
Even fossil fuels owe their origins to the sun; they were once living plants and animals whose life was dependent upon the sun. Much of the world's required energy can be supplied directly by solar power.
More still can be provided indirectly.

The practicality of doing so will be examined, as well as the benefits and drawbacks. In addition, the uses solar energy is currently applied to will be noted. Due to the nature of solar energy, two components are required to have a functional solar energy generator. These two components are a collector and a storage unit. The collector simply collects the radiation that falls on it and converts a fraction of it to other forms of energy either electricity and heat or heat alone.
