If you are not very familiar with switchmode devices then you may consider building a linear power supply ..
Here are examples:

(for <10A without Q5 and Q6)
2) **broken link removed**
(see: High Current Adjustable Regulator)

Thanks Ian for the reply, but i´am too newbie to understant the tecnical link that you send me, but in the other link taht you send me https://ludens.cl/Electron/Ps20/ps20.gif

this is the circuit that i need? i have only to change the T1 to 24 volts? is that or i have to change some thing more?

Thanks Ian sorry for so many questions.

I would change the following:

T1-->20-24Vac
C1-->10,000µF/40Vdc
C2-->1000-2200µF/35Vdc
R2/R3-->may require correction for 19V output ..

And, as I suggested before, you don't need Q5-R9 and Q6-R10 ..
