Hi all,

Can anyone suggest me how we convert square wave to sine in UPS/Inverter.
Or how we get sine wave in UPSs.

Please reply

Thanks and Regards

Active filter.

 

As thingmaker3 has stated, you can use an active filter to remove all of the unwanted frqeuencies that make up the square-wave leaving the fundamental frequency. An active filter with a low-pass response should work fine if you need to preserve the DC component of the square wave. You can use a band-pass type active filter to block frequencies above and below the fundamental frequency if you need to eliminate the DC component of the original squarewave.
