power trouble


Recommended Posts

Hi helio,

For every step you lose energy, this is not the way to go. I would recommend only one step conversion to get the highest possible efficiency. Use two smaller (half the size of the car battery) 12 V deep cycle batterys in series (24 V) and buy a new PSU for the PC. Here is one example for ATX PC:  http://www.zantech.com.au/zantech/power-supply-atx-24v-dc/

I hope I make sense.  ;)

Thanks for the advice. And yes I noticed even the car battery does not last
long whith the pc and drive motors not to mention all the other loads I am
runing. I wonder though if I do this like you say, if the overcurrent will shut
the pc down every time my robot runs it drive motors. They use alot of
curent. They are powerwheels gearboxes.

Hi,
why you used a standard PC board, why you dont use some industril on board PC. Many of them use only 12 or 12 and 5 V. Something like a Arbor EmCore 615, this is Via based PC. Has a many other company that produce this type of board, they is not very big, used only one power suuply, n some case two, and is mre reliable. The ony one disadvantagem the price is higer :)
