Hi
I have a design requirement and are having an issue of designing a method to achieve it
I have resistive elements that change with temperature and generally start with slightly different resistances in any case, what i need to achieve is a way to balance the resistances or a method to maintain the same volt drop/current input to the resistive elements to maintain an even load and output.
The power supply I am using is a constant current supply across the elements however due to the resistance differences they get loaded significantly differently.
has anyone worked on or produced something that can overcome this issue in the past? my initial thinking was to use inductors and dividers so that if one element was drawing more current then it would add inductance to itself relative to the other elements potentially based off volt drop but I'm not 100% on how I would go about this or even if it makes sense to do and there being a better way to achieve the same outcome
Thank you
JD
