Hi there, I'm a software developer who has a project in mind that, in my simple world, should be easy to accomplish with today's availability of technology. However, my knowledge of all things electrical is so pathetically dismal that I'm not sure where to start.
What I want to do is use my PC to influence several different power outputs. That is, I want to control the voltage, current, frequency, etc. dynamically, and I want to do this simultaneously to different power outputs. The software to do this isn't a problem since I want to write my own anyway, but I need to find some sort of RS232/USB/Serial/Parallel-port interface to SOME kind of hardware that can do this.
I could be using the term wrong, but I believe creating a power supply that is variable like this is called a "bench" PSU. I'm unsure about the specifics of whether I need AC or DC, but my very embarrassing blind-spot of knowledge tells me that I will need DC or "step AC".
*blushes profusely*I was hoping this group could point me in the direction of some kind of ready-made product or even a TERM to refer to what I'm talking about, but it seems like using PC's to control power delivery just isn't done. Am I off base?
I know that naiveness can irritate a group of professionals, so I apologize for mine
Thanks in advance for any help you can provide.
