power/ current booster

First, you need to understand that a transformer does not "boost power". The amount of power out is equal to the amount of power in, minus losses. Keeping that in mind, when you step up voltage the current must decrease by a proportional amount since power is the product of voltage and current (and power factor, but we will ignore that for now).

With respect to your example, 10KW at 9V would require about 1100 amps to the low side windings of your proposed transformer. Did you realize that?

What exactly is it that you are trying to do? What type of source do you have that provides 9VAC?

Hello Mark684

The "Guest" is going to make an inverter with a transformer, then run his home from a 9 Volt battery that is his intention.

We had this similar question on CR4, also from a "Guest", a few weeks ago.

As you are aware, the Question is quite nonsensical.

Kind Regards....

I'd at least start with a 12 volt truck battery.

Hello Ricky M. Visto!

Disregard what all of these clowns are talking about. All you need to do what you want is a flux capacitor. You should be able to find one at Doc Brown's.

Stinky Pete could fix you up with one.

Don't forget to get it going 88 MPH.

Well let's see...

9V alkaline PP3 battery, typically 550mAh. So assuming you want to run your 10kW resistive load for one hour, that is 10,000 / 220 = 45.45A. the 9V to 220V ratio is 24.44:1, which is what you need to apply to the current as well. Without losses in the inverter, (magical inverter), that means you need 45.45A x 24.44 = 1111A at 9V, confirming the earlier estimate. Divide that by 550mA (0.55A) per battery, you need only 2020 9V PP3 alkaline batteries to run your 10kW load for one hour. Assume about 20% losses in the inverter and you are at around 2500 batteries.

If you connected them in banks of 25 in series and 100 in parallel, you would not even need the transformer!

One drawback however. The price of copper has skyrocketed so the bus bar to carry 1111A is going to be kind of expensive now ... Plus all the labor to drill and attach those little PP3 clips to the bus bars, probably better to have that done in Asia somewhere to keep the cost down. I could probably build that system for you for about $10,000 US, batteries included!

In case you haven't understood from the previous posts, you are requesting the impossible! If somehow someone could come up with the device you are seeking, it would be worth TRILLIONS!

Energy (the product of power and time) can not be created, only changed in form, and all known energy conversions (like stepping up voltage, at reduced current) have losses, usually in the form of heat. You must have an input of energy greater than the output due to those losses. Where is your energy coming from?

By the way, please send a picture of your AC battery...

Point taken. In our sarcasm, we delved tool far into assuming this was about powering something from a 9V battery, but of course, there are few viable sources of 9VAC around, so that was a logical leap.

Still, forget the DC part of this. It is still 1111A at 9VAC to produce 10kW at 220VAC. No getting around that part. What is the source of 9VAC that can produce 1111A?

Hello JRaef

<"....What is the source of 9VAC that can produce 1111A?....">

Logically, it comes from the 9 Volt battery, which charges a supercapacitor, then that runs the inverter I mentioned above, for a short fraction of a second, providing all the low-voltage conductors had sufficiently low resistance.

All it needs is a wee bit of tinkering, and he will be able to run his house and a couple of cars too, on the voltage/power increase, plus enough to run the battery factory needed to supply the 9 Volt batteries, and then he should be able to retire early, after making a fortune exporting the surplus electricity to the local Electric Supplier's Distribution network.

In all of this, you just need to think outside the square = both literally and laterally.

And take advice from this New Zealand Government graphic:

What is the source of 9VAC that can produce 1111A?

Why Hoover Dam of course. Of course we would need one helluva dropping resistor to get the voltage down to 9 vac... with enough power dissipation to ensure global warming.

what you are talking about building is a switch to turn on and off rare earth magnets and collect the energy from the coils that the magnets create as the fields fold back into the core.

is this what you are looking to build ?
