This inverter circuit can provide up to 800mA of 12V power from a 6V supply. For example, you could run 12V car accessories in a 6V (British?) car. The circuit is simple, about 75% efficient and quite useful. By changing just a few components, you can also modify it for different voltages. |

Realicé el circuito y proporciona 12v a la salida con 6v en la entrada, el problema surgió con diferentes cargas la tensión cae por el piso. Intenté con un pequeño ventilador de refrigeracion de microprocesador 12v/200mA y la tensión de salida cayó a 7V!!!! I made the circuit and provides 12v to 6v output at the input, the problem arose with different loads the voltage drops on the floor. I tried with a small microprocessor cooling fan and 12V/200mA output voltage dropped to 7V!! | ||
how 6v is converted into 12v in this circuit?please tell me the answer | ||
I made a 6V to 12 V converter as posted by you but the only problem i am facing is that the dc voltage isn't boosting more than given i.e 6 V..What could be the problem?I looked everywhere on the internet to solve the problem. | ||
On any supply voltage above 6V, you risk reverse bias damage to Q1 and Q2 base-emitter junctions. (put fwd biased diodes in their emitter to ground connections) (all multivibrator circuits have this problem) | ||
AFAIK L1 is just a choke to stop switching noise from going back to other equipment and causing interference, so i'ts not that critical (unless this device is used with sensitive equipment......or not...)... | ||
What is the inductance of L1? Does it have to be exact? | ||
Hi just built the cct and it works a treat. Ideal for the job it's going to do. I did use a BD122 instead of the BD679, simply because I had one. Thanks a lot. | ||
sir tell me how to made an L1 | ||
Why inductor L1 is used in this circuit??? | ||
if i put bd139 in place of bc547 what happen. please send request to my email. | ||
is it possible to connect this circuit to car 12V supply to get 24V @ 2A | ||
Hello everyone I wanted to know if this scheme works because I put it in and throw me out scooter 6 volts alternating and I Servino 12 volts to charge a 12 volt battery always and some neon | ||
Hi i am just 12 years old and i made it work. But this circuit doesent seem to be efficient it only charges the capacitor with the 12 V inverted voltage. So this project lackks of amps. This is useful to low power 12 V appliances. | ||
Hey could you give me a little more info on L1, such as actual inductance or what core you used? | ||
Thanks for your stupid circuit, Iv got some problem with reading this... 1- Any punctual value for darned L1? 2- Why you didn't connect ground together? | ||
hello. i am trying to understand how things working.. you said that the circuit will require about 2A from the 6V supply to provide the full 800mA at 12V... if you use smaller amperage from 2A like 100mA and convert the current within the circuit, you cant get 800mA at 12V? i am looking forward for your reply Thank you | ||
It is Working! And the load is 988mA! COULD YOU PLEASE GIVE THE ALL DIMENSIONS OF FERRITE CORE ?? regards | ||
how to make the coil L1 please give to me the clue | ||
I build it and the results are very good, I used the centerring of an old car-amplifier to make the coil and put 80 turns of 0.8mm D3 became 15V and the output is 15-16V with an input from 7.5-15V It gives al little noise ... it works very good with only a few comonents. current is 0.75A | ||
Hello everyone, Let me know that I have to perform changes to your model, to build a converter from 5V to 12V. why would I need to take power from usb port of the laptop and maintenance of an antenna that operates at 12V and consumes only 6W. Could you help? Thanks in advance. Luke. | ||
Is there any way to reverse this circuit? to convert from 12V to 6V? i've been checking out voltage stabilizer circuits and i found a few good ones but i have no idea what ratings too look for in resistors and diodes etc. any help would be highly appreciated. thanks, | ||
hey i cant seems to get the circuit to work... i bought the parts and wound the custom inductor... mount it on the circuit board it cant work... output voltage ard 1.53V? any help? | ||
its a great circuit and would be very useful. | ||
Pals
How can i do a converter from 10V to 12V?
Best Regards! (Editor's notes: The same way as this one is built.) |
||
i have a 20 amp transformed and rectified 24v supply and would like a basic schematic to covert to regulated high current 15v dc and have plenty of 2n3055 transistors handy.thanks | ||
NICE! it won't be very efficient, but it WILL be fun! Use a filter on the output and input and put in a shielded box... | ||
HOW TO CONVERT DC 6V-DC24 VOLT, PLEASE E MAIL THE CIRCUIT DIAGRAM AND COMPONENT PROPERTIES | ||
i understand this concept & i like it. | ||
I am a beginner in this field and have visited this website for the first time and have found it excellent,you are doing just a marvallous job. | ||
what is 40mm, the ring diameter or the whole inductor diameter?, what would happen if i use a smaller or larger inductor? | ||
ok...I have a question, I have a specific project that I need to make a HV (100-120Vdc) from a120vac -500 watt power supply. I can get the 100vdc threw a full wave bridge rectifier...but not stable at all. I need extramely low amps...no more than 3, but would like to maintain 100-120VDC out for motor use. Can anyone help me here? Send me an email directly...Thanks | ||
I'm beginning learner. Please show me how to do 24V to 12V Converter and 12V to 15V Converter. Thank you so much. | ||
Aleksander, Wook is right. You can't build that circuit. Even if you did change out the inductor it would be impossible. 10Vdc * 20mA =0.2Watts for the input. 12Vdc * 0.36A = 4.32 Watts. for output. Output power cannot be greater than input power. An input of 10Vdc converter at 20mA outputting 12Vdc can output at the very most, 16.7mA. And that is with 100% efficiency. Realistically you can output maybe 13mA. Also, this circuit is not called an inverter. Inverters take a DC voltage and convert it to AC, so I don't know why it is named inverter. The correct name would be a Boost DC Converter. | ||
we have a '53 chevy truck w/ 6 V system is there a way we can boost this to 12V @10Amp? or can u build us one? we will pay a reasonable amount for one of these we want to put a 12V rodio into this truck. thanks in advance | ||
Is there anyone who can tell me how to wind the custom made inductor of 80 turns, 0.5mm magnet wire on a 40mm toroidal core, for the 6V to 12V converter? Thanks for ur guidance :) | ||
Thanks for the useful info. I have an old 1930's Harley at 6v and I need to mount a GPS unit to the frame. They all require +12v. Does anybody make a commercial 6v -> 12v converter or sell the parts kit mentioned above? | ||
Aleksandar, Your request is not possible to accomplish. You would have to supply much higher current from the lower voltages. If the boost circuit were 85% efficient, in order to output 12v @ 360mA, then: at 10v in, you would need 509mA current at 5v in, you would need 735mA current The inductor L1 would need to be changed for the different voltage levels. | ||
British cars are 12V not 6V | ||
really u have created a very good website and really u isea of giving a scematic diagram is really a fantastic idea | ||

British cars run at 12v the same as everywhere else! (Editor's notes: Older British cars...Also older North American cars.) |

Hello, do you know how to convert 12VDC to 6VDC? thanks | ||
No a variable would not, it will burn out unless industrial type. You will need a night ass resistor or a regulator would be best, with a small heatsink, linked to ignition curcuit. Oh yeah i live in UK since birth and never heard of a 6volt car system!? | ||
