Power Supply Design
Hy,
I need for a new project a power supply with the followed facts:
U_in: 16- 138 volts DC
U_out: 24 volts 3.5 amps DC
For two different pcb placements in sereies,
it is possible to split the U_in in two ranges:
U_in_1: 16 - 45 volts DC
U_in_2: 50 - 138volts DC
same U_out
It would be fine, if the transformer will be in the same package for both voltage areas. The ratio can be different.
Current ripple can be 40%.
Can someone pleas help me with the design and the controller?
Is a Flyback ok for 84 watt power?
Thanks a lot.
Regards norbert.

Hy,
thanks for your quick answer.
Yes i need a galvanic isolation between source and load.
Can u send me the PISIs project file?

Well, let's me know your e-mail and I'll send you my example file. Because on this forum e-mail form I can't attach the file (the same as in post here -only pdf, doc, jpg and so on - so I post picture :-)). And something else - in my example I don't optimize schematic parametrs, only try to avoid warning from PIXls program.
Unfortunately specified lower end of input voltage range is too low for our products to operate
Do you need galvanic isolation between source and load? If not you can see SEPIC converter. Yes - you can design it with PIXls Designer.
I'll try to attach design example.
Ble-e. Only pictures...
