I've read and tried to understand the info about ohms & amps & voltage but my knowledge about electricity is limited, except don't mess with it. Electronics is a giant black hole. What I can't get my head round is how a fresh battery reading 4.1 volts can produce 6 volts?  I know something happens when you set the Torpedo to 6 as I did it accidentally when I went backwards from 3 to 6. The result certainly woke me up.  The moral of that tale is lock the setting!

As long as I know how to work something I don’t care how it works, a TV for instance I can watch a live broadcast from the other side of the world but I don’t know exactly how it appears on my TV.

Agreed Cyborg. Its just that my mind works that way. I should have been an electrician or a car mechanic. I was a pen pusher for 42 years.

Basically there will be a transformer of some sort.for example power goes through power lines at very high voltages and then is transformed to lower volts before entering your home.

Thanks Peterl. That makes sense. I wonder if they do Electrics for Dummies at Calder College?

But the question was how it ups the voltage.
We all know the principal but not the theory, how do you get 6 volts from something that is 3 volts.
You can get a box that can run 240 volt appliances from a 12volt car battery .
I know this is an inverter but how the hell can it do that ?

Transformers normally work by one set of coils passing power to another  through induced electromagnetic fields

That’s cleared that up its all so simple now, but we want to know how an inverter works not a transformer

Simple answer (since thats all I can give)

It works kind of like an amplifier and boosts the power coming out. how that micro chip works exactly I dont know but I suppose I will ask elsewhere and report back my findings

Oh click Im feeling lucky Cy ... you know you wanna

Cy,

I'll take a stab at it.

There used to be electro mechanic rotaty inverters, a combination of motor and generator, so 12v dc in could generate 240 volts out, but at a much lower amperage ( you can't create power, volts up,amps down and vice versa).


For small applications they are now solid state, I assume the dc drives a 12volt circuit which has some form of oscillator working at 50 cyles per second so you now have AC and it is a matter of stepping it up with some form of booster or transformer..

Thanks to all, I understand a bit better now. But forget what I said about being an electrician, my little grey cells wouldn't have coped. The pen is mightier than the sword.
