Dear sir i want a complete e book about smps troubleshoot and repair can plz send it to my e mail
Without being able to see your schematics clearly on my phone, your current sense resistor needs to be a low inductance one. A wirewound one will encourage
acca i should first recify the outpouts of the transormers and after conect tmen in series?
or i should conect the secs of the transormers in series
Yes, gate resistor and snubbers!

What do you say
Yes,when rectify outputs and then use in series.
You can use one smps for each rail.
Use schematics from post #44. R16 is CFL torus. Best Uni SMPS i ever build.
1. What does the waveform at the mosfet gates look like?
2. Typically a gate resistor (around 10-20ohms) is used to minimize ringing
Use mosfet schematics with diac its better. I use that version for 2x400W class d AMP. On SMPS i used 2xirfp460 and ETD49 and works very well. And you
as you said i can't conect bipolar transistors in parallel...
i have an idea...
i will make two separated smps on the same
650 Watt Pulse scheme is the same as the Crown XLS 602
Here's my smps,all parts is from at/atx pc psu.I'll tested it,and works great.If it don't start to oscillate,reverse feedback windings (15k resistor...
I am glad to be member of this forum.
I build up my first SMPS using IR2153D.
The schematic is as follows:
