Dear Wrath:
Do you know if your load is a constant impedance (or
resistance)? If so, all you need to do is assure a constant voltage
across the load. If the resistance is variable, you must know the
current AND the voltage. In either case, a simple feedback loop or
loops in Labview should do the job. For a variable impedance load,
you will need to multiply the current and resistance to obtain a power
reading, which, in turn will be used to adjust your output voltage. (
An iterative shift register, where you compare a current value to a
previous value is a simple, stable way of achieving a feedback loop).
I will be glad to work on this code with you.
