Hi. The subject of my engineering work is the design of smps 500W for audio amplifier. I do not know what to choose topology (half vs full bridge). Personally, I would like to build a full bridge smps I would like to ask you what are the advantages of a full bridge over the half bridge,I think...

I did a test at 135V @ 6,7 A, smps heats up very Q2 D/S Q1 D/S what causes these oscillations?

Hi. I was set too low dead time and shutter overlap, I now have about 2.5 uS. source resistor 1R Dren/Source Q1, without snubbers gate Q1 Q2 Dren/Source 500W

Ok. course without capacitor, Dren/Source Q1 (osciloskope 10V/plot,probe 10X) I used a capacitor 4,7nF

Hi. I have a problem with my smps built on ETD54 3C90 ( 24 Turns at primary) 40kHz. Current measurement at the source of Q2,resistor 1R/3W metal oxide increased dead time, osciloskope 0,2V/Dz, load lamp 60W minimum dead time :( and gate I used a coupled reactor 20uH 15A, core 2P80
