hi, i have designed single phase inverter but in the result i got square wave.To get sinusoidal wave i need Low pass filter,
i tried different method but did got the result.
so can anyone suggest me idea regarding designing filter?

For a start, can you post the circuit of your inverter?
Depending on how you are generating the square wave, there are a few things you can do.

One option that might be easier than a low pass filter would be a resonant circuit tuned to the inverter frequency. It could be made to include a transformer function as well.
