    1.5KVA UPS with pure sine wave output 50HZ

    First you will need dual power rails at +/- 170 volts (assuming 120 VAC, for 240 you'll need +/- 340) capable of supplying 1k5VA continuously (more is better).

    Next, the easiest method I can think of is to use a microcontroller with PWM hardware to drive an H-bridge.

    Some feedback to track the voltage and current among other things will help keep it stable.
