Is it possible to generate 220 volts from a simple 1.5 volt battery?

Question

is it possible to do it with a transformator?

Answer 1

Your first answer is correct in terms of steady state conditions but you could produce 220 volts in a transient condition, in the act of connecting and disconnecting the battery, a changing electric current is created.  AC produces a constantly changing current but DC only when as it is connected and disconnected.  If you added a circuit that converts the 1.5 v DC to AC (constantly turngin on and off or constantly switching from +- to -+, your DC battery can produce 220 V via a transformer.  

Answer 2

yeah, it is possible and actually very easy. gary h and Tx77590 pretty much explained it. you wont get anymore power out of it. so what can you run? a 220v TV remote control? 1.5vdc to 220vdc is very easy. the easiest way is to hook the battery to a 1:150 turn transformer through a switch. turn that witch on and off really fast and it will pass through the transformer, making 220vdc. another cool option is called  a charge pump. a third option is a diode-capacitor bank the last two are great for generating LOTS of voltage. have you ever see neon lights on a car? they use charge pumps to make 15000v.

if you want to make 220V ac, that is a little more difficult. simulated DC is not hard to make, although i dont have the space to explain how. it would basically be two of the transformer setups hooked up with a center tap ground.

it is very impractical to generate real AC from DC.(warning science content) the only way to generate true ac is by rotating a magnetic field within a copper coil. this is what makes that pretty sine wave. here is a brief visual explanation: http://www.analyzemath.com/unitcircle/un... select the "Interactive Tutorial Using Java Applet" like and click the start button. pretend that line is north on a magnet rotating in the circle of wire. see how it draws that pretty sine wave? true AC has to have a perfect sine wave.

i hope my explanation helps more that it hurts...

Answer 3

Yes but you need a special inverter circuit to achieve 220 volts from a 1.5 volt battery. It will only last for a seconds maybe like a discharged from capacitor.

**Good Luck**

Answer 4

transformers only work on AC, not DC.

An inverter will convert 6 or 12 or 24 volts DC to 120 or 240 volts AC, but I don't know of any that work on 1.5 volts.

Answer 5

Yes, this is exactly what a photo flash driver does. Link below for a Zetex one that makes 300V from 3V. The Allegro one works off 1.5V for the main supply and uses a smaller 3V supply for the analog section.

Answer 6

Generation is the wrong term.  You can convert the voltage to 220 volt in AC or DC from a 1.5 Volt Battery.  The efficiency would be so bad that it is not worth it.  You could not get enough power out of a little 1.5 volt battery to do anything at 220 volts.  If you are talking a large 12 Volt Battery going to 220 Volt AC.  That is called inversion and can be done with good effect.  You need to consider the amount of Amps you need and the rated capacity of the battery.  If you need to much power then your battery will not be big enough for the power needed.  If on the other hand, you need small amounts of power at 220 Volts, you can do well with an inversion to 220 Volts.  When you tell us a single battery, we think of a 1.2 - 2.0 volt cell (depending on type of battery).  But most people who talk about inversion are talking about a battery similar to what is in your car, which is 6-2.0 volt batteries in series.

Answer 7

Yes it is possible, using a switching converter circuit, but that is not something you can buy off-the-shelf.

The current you could draw from it would be tiny, because the power output has to be less than the power input. Since power = volts x amps, if you multiply the voltage by a number you have to divide the current by a greater number.

Answer 8

Yes, but you'd need to convert the D.C. from the battery

to some form of A.C. before you transformed it, and you'd get

very little power out.
