Paralleling semiconductors started
Dr. Slack, Thu Dec 18 2008, 11:54AMSeveral threads are all covering paralleling advantages/precautions, so let's gather the advice into one place please. Anybody care to wikify and reference my first throw-down?

Link for convenience:
To clarify the BJT section, it should probably be said how current sharing can be forced (eg: 0.1ohm resistors). Perhaps you could use http://i139.photobucket.com/albums/q297/aonomus/5reg.gif (from http://www.qsl.net/yo5ofh/hobby%20circuits/power_sourse_circuits.htm) as an example of constant voltage on the base with resistors on emitters.
Also I remember in a recent thread about someone's voltage shunt controller it was addressed that HEXFET's in particular had a certain manufacturing process which hindered proper current sharing.
And one last thought, should there be a section about reasons to parallel semiconductors over getting bigger semiconductors, as well as a section for applications?
