Increasing the current capability of this circuit

The diode symbols are diacs symbols which means when the input voltage reaches the combined 3-x voltage the diacs will fire. If the resistances is too high the holding current isn't enough and the diacs will turn off, like a relaxation oscillator. It appears the remaining diac is if the circuit is connected in reverse it will fire through D7.

Why do you want more current? What is the problem you are trying to solve?

I have been asked to find a way have more current capability without increasing the resistance of R1 and R2... the circuit is meant to be a High Voltage sensor. Thanks for any tips

Yes but you didn't explain what your objective is, more current for what? Sure you could decrease the value of the resistors but then the DIACS might have enough to stay on and defeat the purpose of the circuit.

What specifically are you wanting more current for? Do you know? There are way to amplify current but without understanding what the problem is that you are trying to solve it is difficult to advise because you might create a new problem that doesn't exist. That's what Engineering is.

We are trying to see if we can add components to the circuit but they seem to have a higher current requirement than what we can handle at the moment with the current configuration.... we are trying to keep the design secret. Any ideas on increasing current will help and be used for research. Thanks

I have to know what the source is capable of supplying 1st. 2nd I am not interested in stealing your secrets.

So with the extra current, how much are we talking about. Those DIACS, what are the firing voltages?

Maybe increase the current capability of the circuit by around 25 percent?
Each Diac is 26 V firing

Here is what doesn't make sense with the circuit. You have two paths, one is 75V (3x 25V DIACS) then you have the second path is 28V (1 DIAC & 3 LED). the LED path will always fire 1st. The 3 DIAC path will never get to 75V. What is that path for?

The reverse path is 26V, actually a 3rd path, will fire at about 26V.

hello?

What I am looking at, there is no Q7, there are 4 DIACS on regular diode, 3 LEDs and two resistors.

You want to increase the current, yea sure lower the two resistor values. You get what you get. Now keep that a secret.

Get someone else to help you, You are wasting my time!!!!

Any ideas without having to increase the value of R1 or R2 (they are 2M and 1M each)?
D1 , D2, D3 are diodes that let voltage pass when its 24V or above.. the LEDs are just indicators of High Voltage... the more voltage the more they lit.

I just came to this forum for help not for having someone questioning what I am trying to do. Now with all due respect .... is there anyone out there who can give me ideas on how to increase the current capabilities of a circuit that would be great, Thank!!

There is no circuit diagram showing on your message at present, only an image that says, "CAN ANYONE HELP ME PLEASE".
Would you like to re-post the diagram ?
