Voltage Multipliers

08/10/2009 11:56 PM

I have to run a circuit for which the minimun input dc voltage is 3.5V but i have a battery of 1.2V so i want to get a circuit to triple the voltage(1.2V).

can anybody give cicuit related to this topic ?

Buy two more batteries and wire them all in series?

It is highly inadvisable to post an e-mail address in an international forum. E-mail addresses are easily harvested by spambots. They quickly bombard it with advertisements for non-prescription pharmaceuticals, scam requests to update on-line banking details, links to matters of an intimate nature and scams purporting to be about getting large sums of money out of Nigeria, rendering the address practically useless.

The easiest way to do this is to put three 1.2v batteries in series, but if you want to turn this into a project, then this site has schematics for several DC Boost Circuits using just about every method one could imagine to light an 3.3v LED with a single AA battery:

1. Hook up a switch to the + of the battery and run that wire to a transformer.

2. Hook the - of the battery to the other side of the transformer.

3. Turn the switch on and off very fast.

4. hook up the secondary of the transformer to a bridge rectifier circuit.

5. viola!
