How Does A Boost Converter Work?
Basic Principal:
A boost converter works in two stages, ON and OFF. In the ON stage the Semi-conductive Switch is conducting and current builds up in the inductor producing an
electromagnetic field, this field stores energy. In the OFF stage the Semi-conductive Switch does not conduct and the electromagnetic field collapses. When the field collapses the energy stored
in it can not escape through the Semi-conductive Switch so it goes through the diode and into the load/Capacitor at a much higher voltage. This happens several
thousand times a second via the pulses from the NE555 Timer Chip and the result is being able to charge a high voltage capacitor from a low voltage source.
Below is some aid for those of you who do not know electronics well.
R-Resistor
VR-Variable Resistor (also called a Potentiometer)

## Step 2: Protoboard Boost Converter 500V

This boost converter is for those with moderate electronics experience.

If you have the resources I recommend making the printed circuit board version of this device because it is simpler, smaller, and less likely to fail. However feel free to make the protoboard version if space is not an issue.

This circuit takes up a minimum of 1.75" x 1.5" x 1" and can operate from 8.4V to 31.2V Input and output maximum of 500V safely (for the circuit). I recommend at least a 12V battery input.

DANGER HIGH VOLTAGE
This device can put out lethal voltages and the capacitors you charge can store lethal charges for hours, Please wear Electrician Gloves and Safety Glasses while operating and take all safety precautions

Project Cost:
- $17 + Shipping Mouser
- $5 + Shipping Coilcraft PCV-2-394-05L (Follow the link and type in the part number to buy)
- Average Total Cost with Shipping
-- $35 --

Dimensions: 1.75" x 1.5" x 1"
Input Voltage: 8.4V to 31.2V
Output Voltage Range: 100V to 500V
Output Power:

- 12V Input 36W maximum +-20% Charged 290J Capacitor Bank in 8s
- 24V Input 92W maximum +-20% Charged 1468J Capacitor Bank in 16s

Output Power Measured with 1-2 12V 34Ah Lead Acid Batteries for a Virtually Constant Voltage Source

The Major limitation of how much power can be drawn from your batteries is the Battery Packs ESR

---For Best results used high current rated batteries or Batteries meant for Power RC Devices---NiCd are the best (with the exception of Li-poly)
For The Following Batteries an Estimated Maximum Power can be drawn
ESR = Equivalent Series Resistance = Internal Resistance

NiCD/NiMH
12V AAA ESR = 350-400mOhm 28-30W
12V AA ESR = 150-300mOhm 31-34W
24V AAA ESR = 700-800mOhm 60-80W
24V AA ESR = 300-600mOhm 75-85W

Warning-Drawing too much current from your batteries may reduce there capacity, life, and cause your battery to over heat, Monitor Your Batteries temperature.

Note: The Protoboard holes do not accommodate the MOSFET and Diode pins, drilling a 1/32 hole solves this, although you may have to solder the leads to adjacent pads.

If you have the resources I strongly suggest the you make this Printed circuit Board Boost converter instead of the protoboard one. Making a custom PCB will be more compact and have a much better appearance.
This circuit only takes up 1 5/8" x 1 1/4" x 1" and can operate from 8.4V to 31.2V and output maximum of 500V safely.
I strongly recommend using at least a 12V Battery if you goal is maximum power.
This Version's Size can also be reduced to 1 5/8" x 1 1/4" x 3/8" if the Inductor is placed away from your circuit, as it is in most coilguns for convince. Shown in Picture Below.

## Step 6: PCB Boost Converter 500V Construction

8 More Images

The First Step in PCB construction is to design your PCB Board using DipTrace (click the link and download the DipTrace 2 freeware)
You can also use the PCB Layout Shown in the Pictures Below.
The Next Step is to get the Design onto the PCB, you can do this two ways: Using a Laser Printer (Fast, Easy, and if you can find one to borrow I recommend it) and Hand Tracing (VERY TIME CONSUMING)
- LASER PRINTER -
INK JET PRINTERS WILL NOT WORK
USE THIS LINK TO LEARN HOW TO MAKE A PCB BOARD
Tools:

- Copper Clad
- Industrial Grade or Resist Permanent Marker (Industrial Grade Sharpie Can be found at Lowes)
- Iron / Ironing Board
- Etchant (Ferric Chloride)
- Any Leak Proof Multiple Lock Seal Plastic or Glass Container (Example)

If you happen to have a Laser Printer simply get some catalog, phone book, or newspaper paper. This is the type of cheap paper that is very light and most importantly falls apart in water, test a piece of paper in water to make sure. You'll need to tape the paper to a regular printer feed sheet (Shown In Picture Below) You only need to tape it to the top of the sheet, make sure it is as flat as possible to the printer sheet so that when it is feed through the printer it does not crumple.
Download the File Below ( Boost Converter, SMT2 )( You will need to Download the DipTrace 2 freeware). Open the File and click Print Preview Under FILE. Make sure the Objects Selections are as shown in the Picture and the Mirror Box is checked. Click Print, In the Print Window select Properties. In the Properties window select the graphics tab and In the Darkness Square select DARK.
Feed the Paper with the cheap paper taped on it into the printer and Click Print.
Your Paper should look like in the 5th Picture. Use this to size your PCB and cut your Copper Clad with a Dremel or table saw, cut slowly.
Turn on your iron on and put it on it's highest setting ( usually Cotton ), Wait for it to heat up...
While waiting thoroughly clean your copper clad piece with hot water and soap, thoroughly dry your piece. When your iron is finally heated place your copper clad on an ironing board with the copper side face up. Cut the LASER printed Layout so that it is the size of the copper clad piece. Place the piece of paper toner side down and place the iron flat down on the paper and copper clad. Push down with moderate force and wait a few minutes. The copper clad and paper should now be stuck together. Place the piece, it will be HOT, into a container of warm soapy water and wait five minutes.
After waiting take the Piece and run it under warm water and gently rub the top of the paper until all that is left is the toner. Touch up the Layout with your permanent marker.
GO TO NEXT STEP
- HAND TRACING -
- Copper Clad
- Etchant
- Industrial Grade or Resist Permanent Marker (Industrial Grade Can be found at Lowes, hard to find you may have ask where it is, if you find it somewhere else let me know so I can post it)
- Plastic Container
Print out the 6th picture large scale, use your parts as references and draw the traces with your permanent marker as best you can. This will be tedious so be prepared to spend several half hours doing even simple traces.
Seems Simpler huh, It's not.

Just curious but what is the frequency the 555 -timer outputs? I tried calculating it but I always got too high (209Hz) so I think I've made a mistake. It's probably 50-60 Hz.

Awesome tutorial btw! Very detailed and well made. All safety (etc.) things are also mentioned. Thumbs up from me for that.

How would I modify this scheme to input 12vdc and get a series of DC voltages like, 1.5v, 8.4v and 90v? Is it possible to use Zener's across the output to break out the voltage taps dedired? I'd need a max of 5o ma current flow for this radio battery pack.

I'm going to have this circuit built for me, because I'm not that comfortable with circuit-making myself. So I wanted to ask : will any inductor, with similar specs as this "PCV-2-394-05L" thing, work there?

I know, it's kind of a dump question, but I'd rather ask it, than have the circuit blow up on me.

hi, i just built this and im having some issues, though im not sure if it is, but i feel it may have something to do with me using an L7812cv instead of lm7812act.
Anyway, whats happening is that the fet seems to wind up locked between on and off, and what happens here is that the voltage climbs only very slowly, and the mosfet starts to generate allot of heat. i think the 555 at this stage just outputs a constant high. any idea on how to solve? at voltages like 150v the 555 has no issue bouncing the voltage up with a few buzzes every time it drops to below, however, once im getting over 200v it seems to get stuck and its really annoying, i might just try modding the circuit to disconnect the power supply to the 555 instead, so that i cant have instances where the lm393's light is on, as well as the 555. perhaps i should setup the 555 to output constantly

Would it be possible to put 2 or 3 DC-DC HV Converters in parallel to decrease the time it takes to charge a capacitor bank;as you did in your other Instructable with the camera circuits????

Reply 13 years ago on Introduction

What most people do to get more power out of their boost converters is to use two inductors, two output diodes, and two MOSFETs. The output of the 555 timer is fed into a MOSFET driver (like the TPS2813) with an inverting and non-inverting output. The two complementary outputs are fed into the separate Inductor-MOSFET-Diode configurations which doubles the output power capable with a single boost converter. The 555 would have to be setup to provide about a 50% duty cycle which means that you will have to redesign and test different inductors to get the correct output and efficiency. I would not recommend putting two separate boost converters together as they will not be synchronized and therefore disrupt each others frequency and the combine output would be different each second it is operating. Another thing you can do is use the LT3751 chip from Linear Technology, the data sheet guides you through the whole design process and you can get well over a couple hundred watts if you have batteries capable of it putting out that much power. This is the chip I am using for any portable coilguns or railguns I'll be making in the future.

I need to convert a 6v 4.5A battery into 12v that can give around 2A or more current.
Any schematic? Voltage doubler circuits on the web gives around 100mA which is not sufficient for motor driving. Thanks...

they are an ace little chip from the specs. i got a couple free samples, and a breakout board to solder to.
complete failure.
chip kept coming off the breakout board, and since the tracks are so fine, they got ruined pretty quick
dont suppose you know of an equivalent in a more reasonable package rather than those damn smt chips?
