convert square wave inverters to sine wave inverter


Posted on Feb 6, 2014

There`s pretty easy to make squarewave inverters` circuits in the internet. But to run most load like fan, TV, etc you need to have a sinewave inverter. Making sinewave or near-sinewave inverter is more complex and costly. But we can also convert squarewave inverters to sinewave inverters. A LRC resonant circuit is needed for this. The values dete

I am from Bangalore have a 15 yrs old 500 VA trimmed square wave inverter in still working condition. But I can`t use it now as it can damage new generation appliances may be due to the frequency problem that doesn`t match. I`m designing a frequency doubler using PLL LM565. The output of the PLL is a square wave ranging at high frequency (MHz). How can I convert this square wave into sine wave With this cct you have, it doesn`t seem to work well in high frequency. Hi Arup, I have a 350w (500w peak) 230v Inverter. Would this mod work for my unit To do the modifications should I just double the current rating for all the components your site is very useful to us. i want to generate pwm by comparing triangular wave and sine wave. I have tried to generate triangular wave by using IC 741 & LF347. but i couldn`t get the output. Is there any other IC to generate triangular wave. Please help me
