What Is A Power Inverter – It’s Functionalities And Applications

what is a power inverter

What is A Power Inverter? A power inverter is an electric device whose basic functionality is to convert direct current power source to a conventional alternating current power source.

After being converted from AC to DC power. These power inverters are further being used to convert DC power from other sources like solar panels, batteries and direct current transmission with high voltage.

All of this is in turn converted to an alternating current which is in turn consumed and used for a variety of functions like running appliances, electrical product, and tools. These AC power from a power inverter can be used at home and other commercial purposes.

Functionalities Of A Power Inverter

The main functionality of a power Inverter is to convert DC voltage to AC voltage through a rectified process known as the contra-variant process.

There are three types of inverters that can be used to carry out this process and functionality. All these inverters vary based on the waveform of the AC output waveform.

The three types of inverters are : Step wave inverter which is also known as Modified sine wave inverter, Square wave inverter, and Pure sine wave inverter.

Application Of A Power Inverter

The application of a power Inverter varies. Because of the huge benefit of a power inverter, it can be applied in a variety of places and jobs.

A power inverter could be applied in the :

Running Of Variable Frequency Motor Drives:

While applying the power inverter for variable-frequency motor drives (VFD), the power inverter converts from the power from direct current to alternating current power.

The inverter also provides a medium for the control of the frequency and voltage produced by the alternating current power.

Running Of Solar Panels:

Depending on the type and size of an inverter, there is a provision of bigger inverters, which can run throughout on a Twenty-four-volt direct current and even currents with higher voltage.

Contemporary and technologically speaking, a lot of brands and people are embracing the Solar panel and power system, and batteries are slowly and gradually becoming less a thing of interest. Why Solar power is accepted compared to batteries, it is more affordable and economical.

In Solar panels, inverters used as Solar panels need to convert direct current to alternating current. For this conversion to take place, this Solar panel needs the aid of an inverter. And this is when the power inverter is applicable, to convert DC to AC in Solar panels.

Use Of Fuel Cells:

Just like the Solar panels, fuel cells produce direct current power. Which needs to converted to alternating current control for a variety of use.

Especially the use of electronic equipment and tools. And because they turn DC power to AC power. They need the help of an inverter to aid in the conversion of DC power to AC power.

Use Of Uninterruptible Power Supply (UPS):

Uninterruptible Power Supplies, UPS, are a viral electronic tool found almost in every residential and primarily commercial place. They are now as common as stabilizers.

Due to safety and other factors, there is a considerable need for uninterruptible power supply. Especially for very delicate electronic equipment.

A UPS functions through the use of a battery set and an inverter to provide power when power is not available. How the UPS works, is that it charges itself and stores up electrical energy in the battery.

The converter in it aids in converting these stored charges from DC power to AC power. So when electricity is not available, one can make use of the stored charges for electricity.

Use For Extended Power Supply:

In some countries where there is still a shortage of electricity, an inverter is essential as it would help in the running of daily activities that require the use of power.

It could be used in cases of emergency and could come in handy when the electricity is no longer available, and there is still work to do. In such cases, as mentioned above, the need for a power inverter is a definite necessity.

Benefits Of A Power Inverter And Reasons You Should Get One

The power inverter has numerous benefits and it is advisable to have one. As long as the product is of a premium quality and efficient, you get the following benefits mentioned below.

Extended Power Supply:

With this, you don't need to worry about a file that is not backup or the need for the day because you have backup power to carry on with your activities the day.

Affordable And No Running Cost:

With generators, you need to bother about fuel, diesel, etc. But with inverters, all you need is a charged inverter, and you are good to go.


A right inverter is silent. With this, you can focus and not have to deal with the stress that comes with noise pollution.

No Fumes

You don't need to trouble yourself with the hazards of other power supply machines like generators. The inverter has no fumes and can even use inside the house. With an inverter, say bye to the stress of air pollution like dangerous fumes. 

No Oil Spillage:

Inverters are very safe; unlike generators, you don't need to bother about Oil Spillage, explosions, and any of those electrical or careless hazards.

Energy Conservation:

Inverters aid with the conversation of power for use.


Hope so it is clear about what is a power inverter, it's functionalities, and applications. Power inverter is an essential for out daily life with good impact.
