Technical FAQs 4

What are modified sine wave inverters?

Modified sine wave inverters are the most common type of inverters available in the market. They are also known as modified square wave inverters or quasi sine wave inverters. These inverters produce an output waveform that is a stepped approximation of a sine wave. The waveform consists of a series of square waves with varying pulse widths.

What is a sine wave inverter?

Inverters are devices that convert direct current (DC) into alternating current (AC), which is the type of electricity used in most households. There are two main types of inverters available in the market – modified sine wave inverters and pure sine wave inverters.

What are the different types of sine wave inverters?

The square wave, modified sine wave, and quasi-sine wave all have a number of harmonics, which, as you know, are sine waves with frequencies that are odd multiples of the fundamental frequency and different amplitudes. Harmonics are especially troublesome in some applications, so high-quality sine wave inverters are the most widely used type.

Is a pure sine wave inverter better than a modified sine wave?

Pure sine wave inverters, on the other hand, have a lower level of harmonic distortion, ensuring that all connected devices operate smoothly and reliably. In terms of efficiency, pure sine wave inverters are generally more efficient than modified sine wave inverters.
