I have made a wind turbine with a three-phase generator/motor. It puts out great power but its useless unless I can overcome the problems. Its 83volts ac max between two phases in a good wind. It needs to be left unloaded under about 25 volts ac so the blade has enough momentum to get started and not stall. If I rectify it directly to a 12v battery it produces about 100 watts, - to 24v = 200 watts and if put into 48v
(4 batteries) up to 500 watts. Problem is it needs to go into a 12-volt system. Three transformers? MPPT like on solar panels? Or is there a fancy regulator? What old appliance could have a suitable transformer?
(to fit into a students budget if at all possible) It looks like it could put out up to 40 amps total, would one transformer have to handle a third of this? I’m estimating the transformer ratio to be 4/1. Also it seems to put out best power in star, this increases the dc-rectified voltage so I am not even sure if that ratio is enough. Well its just a lot of head scratching for me so I really appreciate any assistance :roll:
