Solid State Orbo System

[Magluvin]

Thanks again Rave. just uploaded another vid with slight variation in caps and freq and no. of magnets, and I increased output and decreased input some also. Need .55w to break though the barrier. Hmm thats 110 ma on the input. This run was about 850ma 5v in so if I can get it down to 750ma or output up some, I could say Unity.
I need to work on it. It has a pretty good freq range of operation, 100hz to over 10khz. It looks like between 5k to 10k will be the better.

Here are some improvements to the dual orbon.
The first pic is of the idea to have a path for the flux at the top of the magnets when the toroid is off. Just so it doesnt become attracted to the pickup coil core and interfere with the other magnets work.
Then thought that ferrite tubes around the mag would be neater and have a good path for the flux to terminate when the toriod is (not) on (or also not in use). The tubes are shown in Glass for a better view of the magnets.

Edit   the words in par. are not correct for what I wanted to say. So read around them. I was dizzy for a bit. =]

One more.
This will double the reluctance for same amount of current.

This pic you show is good. I am finding that the longer the core is, the better chance of breaking the field. So making 2 breaks will ensure a good break but just might make a weaker connection also. Will have to be tested. This is why I show the longer ferrite beads in my 3D pic. One other change I might make to my version is longer mags also. But Im not as sure about that as I am with longer ferrite beads.
Your drawing is representative of what I came up with before these 3D renderings, as it had 4 toroids to make a complete field switch to the pickup coil, and I deduced it down to this. Its simple and should work well.

I
I don't see any need of air gap on the pickup side. You want all flux to flow into the pickup for max output. I wonder why you put it there.

The air gap is for a very good reason. If it were not there, when the toroid is in place and not powered, why would the flux bother leaving the favorable path? The gap provides enough break away to jump to the toroid when not powered, and when powered, the flux's favored path is that gap.

Edit   By the way, Im not much in favor of the gaps either. Its just the way that config needs to be to work. In my config above the gaps are unnecessary. We are breaking the flux path at the magnet before any intersections. The gap probably work pretty good though. Most of the toroids I have seen are wrapped with enough wire that it creates a gap anyway.  =]

@Mag,

I agree with air gap issue, as discussed in previous posts.

About the design with two break points, I realized that you can make a better connection by removing the air gap from the pickup side and making curved paths.
