By 220 VAC, do you refer to square-ish waves, or to sine waves?
The peak amplitude of 220 VAC sine waves is 1.4 x 220, or 310 V.
You can send 264 VDC through an H-bridge and get 264 VAC square waves.
And if the load is unchanging, a series LC (of the correct values) will alter the waveform so it resembles a sine wave, while it boosts the amplitude to 330 VAC..
thnx for in time quick response,the load is somewhat near to 15 ampere,kindly intimate the numbers/data of transistors and wattage of inductor to be used .regards
A sinewave peaks at 1.414 x nominal.
At 15A this means a peak of 21 A.
The inductor must be rated to carry 21 A safely, at 50Hz, and 340V peak V. This is on the order of 7 kW.
I have increased the current flow in my simulation. You can use a lower Henry value. The capacitor must have a higher value. These are based on the standard formulae for calculating reactance.
There is an alternate LC filter configuration, where the capacitor is parallel with the load. It's worth a look.
