Bad Wave in Push pull Dc to AC

[azadfalah]

Hello friends


The image below is the MOSFET output wave
The frequency is 50 Hz , the variable pulse width between 20 and 33 percent



How can I get a better waveform?

Thanks

That is correct for the duty cycle shown, when you turn off there is energy stored in the magnetics which causes the Vds to rise to 2x rail where the energy s returned to source, when that energy falls to near zero the Vds falls again to the pos rail, then the other fet turns on and that causes the Vds to rise to 2x rail during the other fets on time ...
