There are literally a bazillion ways to implement a wind MPPT controller. The main two factors to consider are raw generating capacity and type of generator. A permanent magnet generator is going to use a totally different controller than a multiphase alternator. A 300 watt generator needs a much smaller controller than a 1500 watt unit. A grid-connected rig needs a different output circuit than a rig that will charge a battery bank. The devil is in the details, so to speak.
Luckily, this is not brand new technology. There are lots of manufactured units on the market, as well as kits that can be purchased. The r&d work has been done, as well as reliability trials and experimentation/optimization. Regardless of whether you plan on a custom scratch build or assembling something out of key components, there is an abundance of information on the subject on the web. All you have to do is surf and read.
