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.


This is the schematic of the Voltage Inverter

  1. L1 is a custom inductor wound with about 80 turns of 0.5mm magnet wire around a toroidal core with a 40mm outside diameter.
  2. Different values of D3 can be used to get different output voltages from about 0.6V to around 30V. Note that at higher voltages the circuit might not perform as well and may not produce as much current. You may also need to use a larger C3 for higher voltages and/or higher currents.
  3. You can use a larger value for C3 to provide better filtering.
  4. The circuit will require about 2A from the 6V supply to provide the full 800mA at 12V.

6V to 12V Converter
Saturday, September 21, 2013 11:59:59 AM
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!!

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...)...

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.
L1 info?

Hey could you give me a little more info on L1, such as actual inductance or what core you used?

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

6V to 12V Converter
Wednesday, October 08, 2008 9:51:09 AM
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.

6V to 12V Converter
Sunday, July 06, 2008 2:16:07 AM
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.

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!?

Hi, I have an FJ Holden Ute (1955) which has been converted from 6 volt to 12 volt and I would like to use the original fuel gauge. Would anyone be able to tell me what sort of current draw the fuel gauge might draw and would a variable pot do the trip. Can you recommend a converter that might do what I need. Thanks to all that read, Steve.
