How do you store energy creating electronics, Capacitor...?

How can you turn 12v into 120v, without using any more electric current then, 12v...?

Anyone...?

Answer 1

You can use capacitors to do a straight 12DC-120DC conversion:

Wire up 10 capacitors in parallel (the bigger the better...1000uF,300V) to your 12V supply. Then disconnect them all and wire them in series all at once. From the positive side of the first to the negative side of the tenth will be 120V (or close). A switching circuit with a timer and a bunch of transistors could do this automatically for you.

Answer 2

To change 12vac to120vac you need a 1 to 10 transformer. It will have 1/10 the current. I don't know what the other part of the question is.

Answer 3

I guess you are asking how to boost 12v DC from, say, a car battery to a household 120v AC supply.

It's done with a device called an 'inverter'. This first boosts the DC to a higher DC voltage, then modulates it into AC using a driver circuit. It's kind of like a high-watt car stereo amplifier, but it is optimized to make power at a fixed frequency to drive a load.

Answer 4

Your English was a bit contorted but I think I understand your questions.  Forgive me if I misinterpreted your questions.

Storing electrical energy:  Capacitors are often used but are not the only way.  Charging a battery is an obvious alternative.  Storing power in a flywheel is another way.  Motor-driven flywheels are the method used in very large uinterruptable power supplies for buildings (to start a diesel generator when the power goes out).

Turning 12 volts DC into 120 volts AC isn't expensive at all.  You can buy a 100 watt power inverter for you car for perhaps $50.  Power inverters cycle the 12 volts through a switch to form a square wave.  The square wave is then stepped up to 120 volts AC via a transformer.  To keep the power inverter small, light, and cheap, the switch operates at considerable higher than 60 Hertz.  The 120 volts AC is then rectified, filtered, and passed through a 60 Hertz oscillator.

Answer 5

AC use a step up transformer. You will waste some power, perhaps 10%, more at lower power levels.

DC you need a DC-DC converter, which will also waste power.

Store energy in capacitors or batteries.

Much of your question is not understandable, my answers are from my guesses at your questions.
