Title: half bridge Smps wave forms .....
Post by ani on Oct 24^th, 2014, 6:30am

hi ,
i have built a half bridge smps with pfc front end for 2 X 200W class - D . it works fine but the wave forms that i see is troubling me .... Can any one have a look and tell me if i am doing it wrong ..... the smps has a open voltage loop . wat is troubling me is primary waveform at 90% load the wave form should be flat during the dead time which it is not ....

regards
ani

Is your scope AC coupled or DC coupled?
