Any updates on this project? I have an VW Jetta TDI alternator torn apart on my bench now and I'm trying to see what if any modifications I could make to it to increase efficiency. The Low forward voltage drop diodes were my first thought as I posted quite some time ago. Active rectification sounds very promising and could add quite a bit more efficiency. Time for me to go back out in the garage to see if there is any room for me to sandwich a thin but wide diameter magnet into my rotor between the claws to magnetically "bias" the rotor field coil which should reduce it's energy requirements.
