What are the different types of Inverters available?
Inverters are classified into different types based on the waveform of the output AC power they generate. The dominant waveforms generated by commercially available inverters are – square wave, modified sine wave (also known as quasi-sine wave) and sine wave (also known as pure sine wave). A comparison of the three waveforms is shown below:
Sine wave is the most superior waveform (as it matches the waveform of the AC power that we get from the utility grid) and inverters that generate this waveform are typically more expensive while square wave inverters require minimum circuitry and hence are the cheapest. With the prices of sine wave and modified sine wave inverters coming down and the increasing need of providing back-up power and protection to sophisticated electronic devices square wave inverters are gradually being phased out.
