Hello everyone I am new here.
I have problem in half bridge SMPS in which my output voltage is 23v stable which I set through optocoupler feedback. But after output voltage stable when input given around 120 v AC the drain and High side gate goes in bursting mode and not making own smooth.
I just want to know in half bridge SMPS is normal or it is a problem.
Dummy load is 100k and pwm frequency 50khz,
Deadtime 900ns,
The drain waveform and I have is
