I don't understand your statement Doug. There are a number of autos using
SRG Integrated Starter Generators with dynamic braking in European
production and Valeo has a belt driven unit which is supposedly used on
a few
American vehicles. Since a well set up Wankel starts relatively easily I'm
looking forward to someone doing one for aircraft engine use. You don't
have
to go to a 40 V system, 24 V will do just fine. You do need fast switching
100A (10 seconds) devices to run at 6,000 to 7,000 RPM but they are
available.

My statement was in context to the high speeds of turbo compounding.  I have
been looking for info on whether Valeo has actually made a 24 volt unit or
not.  If you know of such a model I would be happy to buy one. I think you
meant mili sec. switching FETs?
