There are less things you can do with these on a wind system. Trouble is, if you have to ask they probably aren't that useful. I take all the old power supplies I can get, but have no use for a three phase motor. I'll never do a conversion. There are so many power supply versions that there can't be step by step project instructions. I find them very useful for the transformers and the switching chips like the TL494. All the designs are limited to a realistic power of about 150W. I'm a firm believer is distributed systems and find it preferable to use multiple 150W regulators on a couple panels each of a solar system.
I like buying 12V inverters that need repair. These are cheap and quite useful for other applications. Surprised I haven't seen projects here with interesting applications.
