Hello,(adsbygoogle = window.adsbygoogle || []).push({});

Suppose we have a square wave inverter, and at the output we put a low pass filter with cut off frequency of 50 Hz, then the output is sinusoidal with frequency 50Hz.

Now lets take a sine wave inverter and at the output we have a low pass filter with cut off frequency of 50Hz, then we get sine wave with frequency of 50Hz.

What is the difference between 2 inverters if we put a low pass filter at the output?

Is it the shape of the current that will be generated on load?
