Hi Friends, I am trying to repair a smps model FSP250-60GHT. This PSU utilizes a CM6800G Active PFC IC. I am looking for the schematic diagram of that smps Device. Is there somebody who can help me?...

I am designing a 3 Phase input Full bridge SMPS, where the 3 phase bridge rectifier is directly connected to the mains supply (AC voltage 400 V line-line or 230 V...
Maybe a bit late for this thread but having successfully built several Viper22 SMPS' the transformer turns indicated above are incorrect (check the specs)
Has anyone here ever gone the route of using a microcontroller to generate the pwm signal/signals required to drive a switchmode powersupply? I have always
In the schematic, what is the purpose of the circuitry between the gate drive transformer secondarys and the igbt gates? My guess is to prevent a short
But my duty cycle can't go higher than 50% and the transformer was calculated for a 45V output so, shouldn't I get 45V at 10A? An EE42 should be able
I am not claiming anything for myself, that circuit was sent to me long time ago by a friend. I even had to find at my PC, and posted it as is.
Original schematic is here:

Enjoy this driver, Hope it helps
Your SMPS is unregulated, so its normal to face voltage drop at 10A, also the voltage drop is just Good!
Thank you, any pointers as far as my schematic?
L2 is and iron powder toroid with 70 turns. I don't have any inductometer so I don't know :/
