Using a step-up (boost) converter and a step-down (buck) converter to transmit DC power over a long distance.

idea is old. see tesla teory.
Schematics ?
Fighting fire with fire so to speak. Increasing voltage at the source to overcome the opposing voltage drop created by the current traveling through the resistive conductor. Nicely demonstrated. Thanks
Rather than stepping up, could you simply start with a higher voltage power supply? I want to run 12v to a 100w (8A) load along a 50m cable. I have worked out I will get about a 50% voltage drop if I were to use my desired 12awg cable. If I simply start with a 24v 5A power supply, can I just throw a 12v buck converter at the load end to cap the voltage?
Julian lett Could you use a buck step up 12v to 48v to run Sanyo Denki fans 48v from a standard 12v atx power supply. Need to run 5 of them for a ridiculous over the top experiment for water cooling rig
How would the boost converter take to a short circuit? It would be tricky fusing a higher DC voltage. Also, any idea if the additional cost of the converters (not much thanks to China) and comparing losses is worth it over spending more on copper?
One major advantage with the converters I can see is the constant stable voltage thanks to auto adjusting on the buck.
I suppose though it's down to the distance, question is though what distance does this become necessary?
you have a pretty nice garden, too!
Wire four 12v battary positive to negitive and the last two termanal at the farest end of each battery one p one neg and you'll get about 48 volt
Bravo, ingenuous idea, I never heard of this is very useful.
hi
i nedd a 12v dc to simetrical 45v dc ? i dont have much experience in eletronic … can you help me ?
( is 2 of this without the power supply )
