Hello all!
I'm looking to do a driver design with a friend, just to help teach ourselves about power electronics. I've done a bunch of reading on the forum, but I have a couple of questions. I'm sorry if they are common knowledge, or if I missed a thread with that info in it already. (I tried I promise.)
We want to build a driver that can drive any of the common diodes across a wide power level. It might not end up being very small, but that's ok. What output voltage ranges are we looking at here? My feeling is around 3-7 volts, but that's a pretty rough guess. At really low currents, especially on a 445 diode, how low does the voltage drop go?
This brings me to my next question: Are there limits to how little power you can pump through a diode? For example, if I tried to run a 445 at 10mW, would that damage it?
Thirdly, is there any consensus on how modulation effects the lives of these diodes? Are high switching frequencies particularly hard on certain diodes, and if so, how high is considered safe?
Thanks!
