Step-up to 16v or Step-down to 12v

[Bump4life]

So what benefits does a 16V alternator has over a 12V alternator if they both can only supply 2400W for long periods?

efficiency. and also make more theoretical power.

to make things simple,

lets say your demand is 2400 watts. 2400 wattis is V x A in dc. if you raise the voltage you decrease your amperage requirement. so if you charge at 14v youll need approx 2400/14v = 171 amps to run "2400watts" inreality after efficiency that would probably be a 2000 wat rms amp.

if you charged at 16 volts, 2400/16=150 amps. so you dont need as large of an alternator, or your alt wont be running near its max.

but higher voltage also means you have the potential to make more power.

to answer your question, the benefit is you dont need as much current. higher voltage, less current. thats why utility power runs at 13kv and 69kv etc, so they can get away with smaller wires to cut costs. cause larger amperage require larger wires.

Ohms law bro.

Also a 16v battery is being charged at 19.5v and rests at 16.8v

2400watt load

14.4v = 166 amps

19.5 = 123 amps

That's a 34.9% reduction in current. This means a lot for high current drains.

It's the reason why I'm going to a 16v setup for my Audiopipe amps.

thats not ohms law bro. thats the formula for power. you just did the same calculations as i did with different numbers. Power (watts) = I (current) x V (voltage).

Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship

I = V/R

did i miss where we got the resistance value from?

i think our only know values were voltage and power.

You're an electrical engineer and you run audiopipe?

Hmmmm.

I can't build an amplifier cheaper than them.

Edit: typo

You should be able to tell they are shit no problem though.

They do rated. Clamped and tested, the THD is a little high though.

I tested the ap30001d under a 2 ohm dummy load for several hours and no burn out.

if ohms law encompasses all those sure, you used ohms law same as i did.

in my mind ohms law is v=IR, or V/I=R or V/R=I. I guess we can further manipulate to include power calculations.

a^2 + b^2 = c^2

e=mc^2

is/of = % over 100

you arent loud. no one cares

Well if you guys want a high current buck regulator (100A or more) I can totally, prototype, test, debug, and then build one for the community.

I would like to poll you guys and see what current you would want with your experiences in this matter.

We have no clue who you are.

so even if you had a product we may be interested why would we give you any of our money for an untested product from an unknown person on the Internet?

I'll post a video on youtube demonstrating the regulator and it's ability to sink current -or- if you prefer, do you know someone on this forum I could send a device to perform impartial testing?

(mind you I do have a full-time job in the microwave (not the oven) industry).

PM me if you want to talk over the phone and have my address.

I primarily asked because I wanted to know if their is niche to fill in this category.
