EXPLAIN INVERTER AND ITS TYPES

In the 19th century one of the most talk of the town debate of battle was not in politics or with swords but for the type of electricity to be used by our buildings. For more information join the electrical training course to make your career in this field.

Distinguish between DC and AC electricity ď ľ

Direct Current (DC) is the main talk over here especially when the science teachers taught the reason behind the electricity generation and it is called as the flow of electrons. It can be considered that electrons are like ants carrying packages of electricity. Switch, battery, lamp are linked by a circuit and the electrical energy is transported from the battery to the lamp till the energy in the battery is discharged.

ď ľ

But the situation is different in the bigger household appliances and the power supply coming along from the outlet is based on alternating current (AC) each and every second the electricity switches direction for 50 to 60 times. It is very difficult to understand how AC provides energy where there is a constant change in its mind about destination.

For instance if the electron runs from the outlet to a few millimeters down the cable then have to change the direction and go back again so the question is how the lamps gets light?

ď ľ

It is very easy to pin down the answer, just consider the cables in between lamp and the wall packed full of electrons. As you switch it on the vibration causes the electron to flow back and forth in the filament of the lamp. For transporting energy the electrons need not mandatory run in circles and in AC the simply run on the spot.

What is an inverter? ď ľ

Most of the appliances is our house are made to run from the AC power.

Devices that require DC but take AC from the outlets has a need of an extra piece called rectifier and it is built from electronic components known as diodes for converting from AC to DC.

ď ľ

It is quite easy for understanding the concept of how it works as the inverter works totally opposite of it. In a flashlight, if you are having a battery and the switch is on so there is a flow of DC around the circuit and it is always in the same direction. But if you change the position of the battery still the DC will flow in the opposite direction. If you are that fast in changing the position 50 to 60 times then you are acting as an inverter changing the battery from AC to DC at a frequency of 50 to 60 HZ.

Types of Inverter ď ľ

If you switch on and off your DC current or change it back and forth as it is keeping on reversing the direction then you will end up with sudden changes of the current all in one direction and all in one direction back again. With respect to the current or voltage if you draw a chart against time and you may find getting a square wave. It can be considered an alternating current, technically. In general terms there are hefty appliances in our homes and all they want is energy and lots of it, so it doesn’t bother the square waves.



There are two types of inverters they are true/pure sine wave inverters and modified/quasi sine wave inverters. True inverters make use of transformers and electronic circuits to rapidly change and they can be used for powering any kind of AC appliance from a DC source which has computers, video games, TV, radios etc.



Modified sine wave inverters use thyristors diodes and other components for producing a rounded-off square wave and it is good for delivering power hefty electric appliances. Thus there is a risk of overheating with MSW inverters.
