What is inverter working?

Answer 1

An inverter is a device that changes or converts direct current (DC) power into alternating current (AC). The inversion process of an inverter can be achieved with the help of transistor, capacitor, resistor etc.

For low and medium output transistorised inverter are suitable but for high power outputs.

The inverter is made up of three major parts namely

i. Oscillator

ii. Transformer

iii. Transistor

The basic working principle of an inverter may be explained with the help of circuit shown below. It is called voltage driven inverter because direct current(DC) voltage course is connected through semi conductor switches directly to the primary of a transformer.

The inverter transform the DC electricity produced by your battery into the alternating current electricity which is commonly used in most homes for powering lights, appliances and other gadgets. Inverter are rated by thier continious wattage output and the capability of briefly sustaining much lighter loads than they can run continiously. If you only have a single appliances or two to run it doesn't take much. For example, to run let's say a 14inch TV, a VCR and a light all at once, total up all wattage about 40W for the TV, 20W for the VCR and 14W for a compact flourescent light, a total of 74watts, pick an inverter that can supply at least 74watts continiously.

To power a house of appliances and light it will take more planning, midsize inverter of 500-1000watts will do a good job running light, entertainment equipment and a kitchen appliance.

NOTE: An inverter produce much heat when it is working, it therefore means that you provide proper ventilation for the inverter to be cooling while working to prevent breakdown of the system.
