building a constant power draw
I need to build a device that draws a constant power (basically, replicating a regulated switching power supply) and know that there's a macro or something that can be written to do this in tina. Can you help?
In Tina you can add a ‘Sources/Current Generator’.
Leo, thanks for the reply, but that's not quite enough.
I know Britt had done a little macro in a training he did. The current generator draws a constant current. I'm looking to build a simple model to look at the input impedance of a power supply (very simple) where it has negative impedance. So I vary the input voltage and expect the input current to vary by power/voltage....thus a constant power sink.
I'll send you what I have. Let me know where you'd like me to send it.
