H.F. Half bridge Sine wave invertor

[mkumarrewari]

Hi, I have +325v & -325v dc voltage.Could anybody help me how to generate 50hz sine output with switching friquency arround 20khz with pulse variation of both channel inversly proportional. Both channels will be regularly on by sine table with dead time. it will be too.. thankful please.

Hi mkumarrewari

Try to have a bit search on half bridge class D audio amplifier . the procedure is exactly the same !
