Hi, everyone.
I'm a hobbiest and I have an older satellite reciver that needs a new PSU.
Since the manufacturer has long since disappeared, I can't order a replacement.
Fortunately, a spare computer psu has all the voltage outputs I need, except for the following three rails (which are regulated, so voltage should not vary too much):
-30vdc @ 900mA
+22vdc @ 900mA
+22vdc @ 900mA
So, is there a simple-to-build (at least not too complex) circuit available that I can take the 12vdc @ 25A rail from the computer PSU and boost it to what I need?
I've search using Google and on this site, but I can't find what I need (at least something that doesn't assume I have an advanced degree in electronics engineering!).
Thanks in advance to all who reply.
