Default Re: High voltage regulator circuit.

Good summary, Dave.

Think of any big semiconductor as a lot of small ones in parallel, then ask how fair sharing of currents and heat is achieved between different areas of the same part.

As we are now in the 21st century, with switch-mode everythings to the right and left of us, the focus is on high voltage semiconductors and high current semiconductors, but not on both at once - high power semiconductors. So trying to find something that will do a bit of heat is becoming difficult.
