This instructable will tell you how to make a voltage multiplier! So, lets get started :)
Here is some info about voltage multipliers if you want to know how they work. If not, then skip to the parts list.
Definition - "A voltage multiplier is an electrical circuit that converts AC electrical power from a lower voltage to a higher DC voltage by means of capacitors and diodes combined into a network." - Wikipedia
My definition - Voltage multipliers rectify low voltage AC to high voltage DC (pulsed). It uses a series of capacitors and diodes to simultaneously step up and rectify the AC to DC. Most of its uses are obviously applications that require high voltages...
The type of multiplier we will be making is called a 'half-wave' multiplier. I think its the simplest, yet efficient for my purposes. full-wave multipliers are more efficient in the sense that, there is less ripple voltage. Basically, ripple = bad, bad = Less current and voltage out. A voltage multiplier consists of 'stages' each stage doubles the peak output of the ACinput. the more stages, the higher the voltage. In this 'ible, I only make a 2 and 3 stage multiplier because my breadboard isn't big enough to support that and its not even rated for that voltage anyway :P
The following is the parts required for building the EXACT replica of my voltage multiplier. you can easily modify to your needs though. Like add more stages and stuff...
six 330VDC 80uF capacitors (you can get them from the single use cameras at wal-mart.)
seven 1A 400v (minimum) diodes (1N4004)
A breadboard, (or something to mount the components)
22 AWG jumper wire or just regular solid 22 AWG wire.
A wall wart- 16VAC or equivalent. (750ma)
misc alligator clips (for temporary testing)
Multimeter (for testing purposes)
wire snips (to take off the insulation on the wire)
Step 1: NOTE!
Proceed to the next step to start building!
Step 2: Schematic
Step 3: Build the Capacitor and Diode Array
try to follow the pictures the best you can, I took so many pictures so that I could explain in the photo instead of words because it will become WAY to confusing if I was saying the letters and number pins the you put the components in.
Make sure that each side of capacitors is linked in series like so: Pos + to Neg - Pos + to neg -
The very first diode goes from ground to the Pos + of C1, then from the Pos + of C1to the Pos + of C2, Pos + of C2 to the Pos + of C3 and so on...
Step 4: Prepare Wallwart
Step 5: Hook Everything Up!
connect the alligator clip ends to the AC input (the Wall wart ones!) and connect 2 alligator clips to the HV out and ground to the multimeter. Turn on the power and your done!! the multimeter should display roughly the AC input 3 * to DC output.
Step 6: END!
