Therefore, it's good to know how to convert a square wave to a sine wave. And this can be accomplished rather easily with just resistors and capacitors. In fact, to build this circuit, we need 3 RC networks. Each RC network is comprised of 1 resistor and 1 capacitor. So a total of 3 resistors and 3 capacitors are needed for this circuit.
There's pretty easy to make square wave inverter circuit in the internet. But to run most load like fan, TV, etc you need to have a sine wave inverter. Making sinewave or near-sinewave inverter is more complex and costly. But we can also convert square wave inverters to sinewave inverters. A LRC resonant circuit is needed for this.
An RC integrator circuit changes the signal output depending on the frequency and could change the square wave to a triangular wave or triangular wave to a sine wave. In this tutorial, we are using these RC integrator circuits (RC filter networks) to convert square wave to sine wave.
Therefore a square wave inverter working with 12V DC would generate an output equivalent to say 330V just like a sine wave inverter operating with the same battery but if you measure the output RMS of both the inverters, it would differ significantly (330V and 220V). The image incorrectly shows 220V as the peak, actually it should be 330V
