Flux..
Won't "ringing" the coils with a chopper (so to speak) make them have a much higher currant peak then normal?
Especially near normal cut in?
And slapping more/less square wave demand across the same genny coils raise hob with the normal ebb and flow of the, again, more/less sine wave pattern?
Looks like it may produce a bit of growl in the genny too, if using the coils for the inductance.
But the caps may have an additional bonux if designed just right outside of helping with the growl/load seen by the genny (and filtering)--capacitor improvement for the power factor. But then again--the PF is all over the place anyway using wind for the driver source.

I am really interested in a boost conveter for my wind gennys--much of the summer they sit turning just under cutin and not doing much good. Outside of the occasional thunderstorm that really tests the diode ratings, on the small one. And if it's just wearing out when it could contribute "something"--it's wasted effort on my part.
I have a rough draft of the main power handling circuit made with your "cutin bypass" type design and am working on the feedback/monitoring now.
It'll use a simple PicAxe 08M controller and have built-in dump load capabilities.
I just wish most of the wind gennys were "typical" instead of each installation being so $%%$ independant/different on the power profile, easier circuit design when one size fits all/most. OOOHHHH Wellllll..
