Phase Locked Loop Implementation

Hi,

I have been looking into using a phase locked loop to detect 3 phase zero crossing points. I have found a very interesting paper (attached) on the subject, which does almost exactly what I want. The trouble is it is a little beyond me.

I was wondering if anyone hase done a similar thing. Any help or advice is greatly appreciated.

Regards
Bob...

I am not sure if the following detector could help you this time, since my controllers drive one bi-thyristor (220Vac or 380Vac).
