Worth a watch.[youtube]http://www.youtube.com/watch?v=x7JDElxCyX4[/youtube]This has actually been my goal for quite a long time. I have two quotes to make custom cores for me but they are pretty steep at 900 dollars.
His explanation on how the bi toroid transformer works cant be as it is in the video. He says the flux travels from one secondary to the other-and vice versa. Problem is,the secondary on the left in the video isn't hooked up(as can be clearly seen in the video)-no load placed on it to create the magnetic flux that travels around to the secondary on the other side I would be interested in what poynt has to say about this?.This has been around for some time now,but as of yet,i don't recall hearing of any solid evidence that confirms the P/in P/out ratio's.
