Pure sine waves and modified sine waves are types of electric waves produced from the conversion process of electric current. They are useful for powering various electronic devices in houses, buildings, and industries.
Choosing the right waveform plays an important role in determining the efficiency and compatibility with various electronic devices. Therefore, in this article we will discuss pure sine wave vs modified sine wave in-depth, starting with the differences, advantages, and disadvantages.

Definition of Pure Sine Wave
The pure sine wave is a type of wave that is usually found in inverters and has a smooth, stable, and harmonious sinusoidal wave pattern. This output wave resembles the main power grid wave and has a total harmonic distortion (THD) of <3%, making it suitable for various electronic devices.
Definition of Modified Sine Wave
The modified sine wave is a type of wave in an inverter with an output that is a simplified representation of a sinusoidal wave, so it has a square wave pattern and little distance between each wave. It has less THD than a pure sine wave and has few limitations in its application.
The Difference Between Pure Sine Wave vs Pure Sine Wave
Basically, pure sine waves vs modified sine waves have differences between each other. Here are some basic differences between pure sine wave vs modified sine wave.
| Pure Sine Wave | Modified Sine Wave | |
|---|---|---|
| Waveform | Smooth and stable. | Less smooth and box-shaped. |
| Efficiency | It has minimal distortion, produces a smoother and more stable current, and is suitable for all electronic devices. | It has minimal distortion, produces a smoother and more stable current, and is suitable for all electronic devices. |
| Compatibility | Suitable for use by various electronic devices, both basic electronics and sensitive electronic devices such as refrigerators, laptops, medical devices, and more. | Less suitable for sensitive electronic devices, but works well on simple electrical devices such as lamps, rice cookers, and fans. |
| Electronic Interference | Does not cause any disturbance. | It can cause disruptions in audio and video, such as noisier sounds or blurry images. |
| Cost | More expensive | Cheaper |
| Durability | It is durable because it is usually equipped with quality components and good protection features. In addition, it can reduce the risk of damage that occurs due to electrical distortion. | Its durability depends on usage, component quality, and device compatibility. |
Pure Sine Wave vs Modified Sine Wave: Pros and Cons
Inverters Pure Sine Wave vs Modified Sine Wave have their own advantages and disadvantages in their application. Here are some advantages and disadvantages of pure sine wave vs modified sine wave.
| Pure Sine Wave | Modified Sine Wave | |
|---|---|---|
| Pros | (1) Produces smoother and more stable output waves. (2) Improves device efficiency and performance. (3) Compatible with various sensitive devices. (4) Prevents damage/malfunction to the device. | (1) It has a lower price than pure sine wave. (2) Can be used in simple electrical devices. (3) Simpler design and easy to repair. |
| Cons | (1) More expensive than modified sine wave. (2) More complex so it requires extra maintenance. | (1) It has less smooth and stable output. (2) Not compatible with sensitive devices. (3) May cause the device to malfunction. |
Conclusion
Based on what has been described above, it can be concluded that pure sine wave vs modified sine wave has its advantages and disadvantages. In choosing an energy supplier, you need to pay attention to the output wave that suits your needs and budget. If you need reliability and good compatibility, then pure sine wave is a wise choice. However, if for simple applications and with a limited budget modified sine wave is the best solution.
