Understanding Sine Wave Inverter | How is it Different from a Square Wave Inverter?

An inverter is a power backup system that helps run the home appliance during power outages. It is essential to have an emergency backup in homes, especially in areas where power cuts are quite frequent. If you are planning to buy an inverter, you need to choose between the two types—a sine wave inverter and a square wave inverter.

A pure sine wave inverter makes use of superior technology to offer extended power backup. It is designed to supply power that is similar to that of the utility grid. In this article, we will understand everything you need to know about a pure sine wave inverter as well as the difference between sine wave and square wave inverter.

Pure Sine Wave Inverter Explained

In the case of a pure sine inverter, the voltage smoothly rises from zero until it reaches a peak. After that, it starts to gradually decrease and changes the polarity as soon as it reaches zero again. This type of inverter reflects the output voltage in the form of sine waves. The smooth output of a sine wave inverter is what makes it suitable to power home appliances such as television, refrigerator, microwaves and washing machines.

This inverter technology is used in video/audio equipment and satellite systems. The wide-ranging usage of sine wave inverters makes it a preferred choice among the masses.

How Does a Sine Wave Inverter Work?

Today, more and more people are using sine wave inverters. Being an inverter, it converts the direct current into alternating current. The mode of operation of a pure sine wave inverter is divided into three stages. Let us talk about each stage briefly: -

  1. Oscillator Stage

At this stage, the inverter generates an oscillating pulse through an integrated circuit. The alternate negative and positive voltage peaks are generated by these oscillations. But they are weak and cannot be used. So, these are sent to the amplifier for the required task.

  1. Amplifier Stage

The voltage generated by the oscillator is amplified to a high current level at this stage. This amplified electricity is in the form of alternating current, and the voltage is at the battery supply level, which is not enough to operate home appliances. We need to raise the voltage level so that it is suitable to run electrical devices. For this very task, the amplified voltage is sent to the secondary winding of the output transformer.

  1. Transformer Stage

In a transformer, the power is stepped down to the required AC levels with the help of magnetic induction. The transformer in a pure sine wave inverter works in a similar manner as that of a power inverter but in an opposite manner. Here, the low-level power from the amplifier is applied to the transformer’s secondary windings. This results in a stepped-up voltage, which can be used to power the home AC appliances.

Difference Between Sine Wave and Square Wave Inverter

Let us look at some of the key features of an inverter and how is it different from the sine wave and square wave inverters: -

  • Appliances Supported

A square wave inverter is generally used to support devices such as bulbs, fans and tube lights. On the other hand, a sine wave inverter is used to power heavy home appliances such as refrigerators, microwaves, computers and laptops.

  • Safety

If we talk about safety, it would be right to say the sine wave inverters are slightly safer to use than square wave inverters.

  • Noise

Sine wave inverters do not produce any noise while they operate. In contrast, a square wave inverter may produce some sound while they are in use.

  • Cost

In terms of cost, a sine wave inverter is more expensive compared to a square wave inverter.

Advantages of Using a Pure Sine Wave Inverter

Here are some of the key advantages of using a pure sine wave inverter: -

  • A sine inverter helps provide an extended power backup compared to other types of inverters.
  • The most significant advantage of using a pure sine wave inverter is that it is built using the latest technology.
  • This type of inverter is more efficient than other types.

A pure sine wave inverter is considered to be a quality inverter that is highly efficient. It can let you power many appliances simultaneously and without any sign of damage or overheating. It is a great investment which will help you preserve your home appliances and save money at the same time. We at Luminous offer a stellar range of quality inverters at affordable prices.
