I have done something like this, but on a smaller scale. Simple approach, run engine at 1/2 or 3/4 throttle, control excitation to control engine revs, if you want more power, REDUCE excitation! No regulator. Use 3 ph bridge, ripple frequency is 360 Hz depending on speed, and alternator inductance / impedance will reduce ripple. I think you will find ripple is acceptable.

Ahh, another useful answer. Sounds like I have some experimentation to do. -- Worlds only All Electric F-250 truck! http://john.casadelgato.com/Electric-Vehicles/1995-Ford-F-250 _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA) -------------- next part -------------- An HTML attachment was scrubbed...
