Difference Between A Pure Sine Wave Inverter & Modified Wave Inverter

Difference Between A Pure Sine Wave Inverter & Modified Wave Inverter

You must have heard about inverters and how they convert Direct Current (DC) to Alternating current (AC). Basically, an inverter converts “raw current” to “usable current”. The inverter acts as a channel because it doesn’t produce any power. It channels power from a DC source and converts it to AC before it can power your appliances. Now, getting just any type of inverter won’t do. Depending on the appliances the inverter will power, you can get either a modified sine wave inverter or a pure sine wave inverter. What’s the difference between the two and which is better, you might ask? Keep reading.

Difference between pure sine wave inverter and modified sine wave inverter

Mode of operation

As the name implies, a modified sine wave inverter is one that uses a modifying circuit to adjust the waveform of the output. In other words, as AC is being transmitted to the appliances, a little adjustment is made at intervals and this causes little “jerks” in the flow of current. However, in a pure sine wave inverter, the waveform is continuous and smooth. No modification is required.


Due to the need to modify the output waveform as current flows, the modified sine wave inverter uses some of the power generated and this reduces the power sent to the appliances. This will affect the performance of the appliances. Most modern appliances will not run smoothly as the power “jerks” will affect the operation. A pure sine wave inverter on the other hand doesn’t not need to modify the AC waveform therefore, appliances using this type will run hitch-free.

The modified sine wave inverter costs less than the pure sine wave inverter and you can guess why. With the advent of new and improved technology that it comes with, the pure sine wave inverter offers more and thus may dig a deeper hole in your pocket but …you pay more to get more right?

Functionality and compatibility

Not all appliances work on a modified sine wave inverter. Some medical equipment may not function at all as well as other appliances like microwaves and motors with variable speed. But all appliances are designed to function with a pure sine wave. They produce more wattage than modified sine wave inverters.

Speed and sound

Pure sine waves inverters are cooler (do not overheat) and are not as noisy as modified sine wave inverters. The best part is that they are faster. The time it takes for the waveform to be modified in modified sine wave inverters is valuable time for transmitting of current in a pure sine wave inverter.

Need we say more? If you’re considering the thoughts of getting an inverter, it’s better to spend a few extra bucks on quality and durability than to be penny wise and pound foolish.
