Inverter – Ultimate Guide to Know how it works

Inverter – Ultimate Guide to Know how it works

Technological advancements and breakthroughs have brought the world closer together. Through the Internet’s power and connectedness, we are all connected to people all over the world. But what happens to these cutting-edge technologies and processes if the electricity goes out? The electricity goes out, as do most of our connection’s mediums. What do we do in these situations? Inverter answers the question itself.

 

Do we sit and wait for the electricity to come back? As much as a break we need from our routines, human beings are innovators. Inconveniences, adjustments and compromises often lead to more technological innovation. E.g. we invented washing machines, food grinders, microwaves and ovens all because repeated manual labor was inconvenient to us all. We were in look for something that would do our work for us. Technology is thus, a result of human laziness although it symbolises human smartness. One such human innovation for not adjusting and accepting the electricity cut is the innovation of inverter battery.

Inverter batteries

 

So, what are inverter batteries?

Inverters are what they sound like. An inverter is a piece of independent equipment that transforms DC to AC voltage. By converting the energy held in dc sources such as batteries and rectifiers, the inverter converts direct current to alternating voltage. The inverter’s batteries store energy as direct current, but the home appliances we use require alternating current, which is how inverters function. The inverter can be used to power household appliances in the event of a power outage or other emergency.

 

In other words, in case of power cut off, the electrical equipment’s at our house stop working because they need active, live current passing through them. When the supply of current it stopped, it is obvious the devices would stop working. This is when the inverter batteries come into picture. They are power storage houses which supply current and bring electricity back to our house, our devices.

 

The inverter can be built as a stand-alone unit for solar power applications or as a backup power source using batteries that are charged independently.

To understand the concept of how inverter battery works, we will first have to clearly understand what DC and AC power supplies mean.

 

What is Alternating Current (AC)?

The electric charge flow in alternating current changes direction on a regular basis. For household equipment, offices, and buildings, AC is the most often utilised and preferred electric power.

What is Direct Current (DC) and how does it work?

Direct current, unlike alternating current, does not have a periodic flow. Current electricity has a single direction of flow and a constant voltage. DC is mostly used to power electrical equipment as well as to charge batteries. Mobile phone batteries, torches, flat-screen televisions, and electric cars are just a few examples. A plus and minus sign, a dotted line, or a straight line are all used in DC.

 

The direction in which electrons flow is the primary distinction between AC and DC. In DC, electrons move in a single direction, but in AC, electrons swap directions, moving forward and then backward.

 

One of the biggest disadvantages of AC is that it cannot be stored. DC, on the other hand, may be stored in batteries.

 

This is due to the way batteries function… Batteries store energy chemically, and the release of electrons occurs as a result of a chemical reaction on one side of the battery, which is then ‘collected’ by a chemical reaction on the other. A Galvanic cell is what this is called. To make an AC current, each side of the cell’s chemical reaction would have to go into reverse on a regular basis, which does not and cannot happen, hence you can only store DC in a battery.

 

The polarity of AC can change up to 50 or 60 times per second. It’s impossible for a battery to change its connections at the same rate!

 

As a result, we don’t notice any AC Batteries!

 

That implies you’ll need a device to convert DC to AC if you wish to run an AC-powered device from a DC automobile(source)/ battery. That gadget is referred to as an inverter.

 

Converting AC to DC, on the other hand, is rather simple. All we need is a circuit with a pair of diodes placed in a specified pattern. A Rectifier is the name for this circuit. Rectifiers are the polar opposite of inverters.

 

Types of Inverter Battery (Only Inverter) Available in India:

There are mainly three types of inverter battery (Only Inverter) available in India. They are: Pure Sine Wave, Modified Sine Wave, and Square Wave inverters.

 

A pure sine wave inverter, like a wall socket, provides clean, dependable, and constant electricity from the battery. In a pure sine waveform, how do inverters work? The current is released in a sine waveform, identical to that of a utility supply, using these inverters. If you wish to utilise various household appliances and other gadgets that demand more power, a pure sine wave inverter is ideal. A pure sine wave inverter provides power backup for several devices at once while also meeting their power consumption requirements; as a result, it is on the more costly side of the inverter market.

 

Multiple devices can be powered by the modified sine wave inverters at the same time. The modification, unlike the pure sine wave inverter, does not provide a totally smooth transition. So, how does an inverter in a modified sine waveform work? During power interruptions, the inverter may have a brief wait before turning on or off.

 

The modified sine wave, despite its strength, can occasionally degrade the efficiency of household appliances. This might cause the lights to fade or the appliances to make a buzzing noise. These inverters are appropriate for appliances that have a resistive load and do not require a power spike during startup. Modified sine wave inverters have the advantage of being less expensive than pure sine wave inverters.

 

The square waveform: These inverters produce a square-shaped waveform, as the name implies. In comparison to the pure sine waveform inverter and the modified sine waveform inverter, the square wave inverter is less efficient. If you simply need to connect a few devices to the inverter, this is the inverter for you. These are easily accessible in the market and are inexpensive. A square waveform inverter, on the other hand, might be troublesome since these devices are loud.

 

FAQs related to working of an inverter battery:

When should we use an inverter?

When there is a power outage or a power cutoff, the inverter transforms DC electricity from the batteries to AC power.

 

What exactly is a power inverter?

A power inverter is a device that converts bulk DC electricity into AC power for use in the power system. At the receiving end of HVDC transmission lines, for example, power inverters are utilised. A grid-tie inverter is the name for this type of inverter.

 

What exactly is a kVA of inverter?

The kW (kilowatts) and/or kVA (kilovolt-amperes) ratings are commonly used to “size” UPS systems. A 1 kVA UPS, for example, has circuitry that can withstand 1,000 volt-amperes. A 1kVA UPS from N1C, for example, can power 900 watts of connected equipment. This translates to a “power factor” of 0.9 for the UPS.
