I have a dc PSU which gives 110V rectified at its output. I need 48V from that power supply. There is no space for step down transformers.. can I use a transistor such as 2N3055 based circuit to get the required output..?? the out doesn't need to be regulated just in the vicinity of 48V +-3V. The current load will be around 10Amps. plus it will be on for atleast 8 hrs in one go. Fan based cooling is already available in PSU case + space for a 3 x 4 x 1.25 inch power board.!
I do not have access to high side voltage regulators.. but can get any type of power Transistor (Well mostly any type!).
What I had in mind was something like a voltage divider feeding the base of a small pn transistor and that inturn driving a large NPN or preferably a PNP power transistor (or number of transistors in parallel) to get the required voltage output.
Am I going in the right direction or or going to gaga land..!!!!!!
Any +ive ideas, suggestions and/or schematics are welcomed.
Cheers all
