how to convert a square wave output from SG3524 to sine wave using op-amp or...

Perhaps you can configure the SG3524 to input a sinewave of the desired frequency, (I assume 50 or 60Hz), such as from a phase-shift sine-wave oscillator, to the IN+ or IN- inputs to generate a PMW sinewave modulated output.
This output can be LC filtered or run through a transformer to give a power sinewave output at the oscillator frequency.
Here's a circuit that attempts to do that but it apparently has some problems with the output circuit.

Please Post the LC filter circuit diagram if you have
