Agentgates´s TPU setup with strange wavehill hump

Thanks for the reply. Yes indeed, we built so many coils that was almost like a lifestyle.
And don't worry, now I'll finish this thing in a couple of days and when I have the multiple channels I will get rid of the IGBTs and the heatsink and I'll tickle the electrons to keep them flowing continously. Actually we will get almost a stable DC output at whatever load.

Very nice coil! Hook it up, but make sure you use well oversized FETs and NO flyback diodes to save the DC PSU. The power drop will be high on the primary side due to Lenz law, will need to decrease the turns on the secondary and keep spaces between them. It has to look like a twisted fishing net and the primary-secondary have to cross each other only on a tiny "dot then space and dot and space again" manner. It will acually create an "electron tornado" in the secondary wire and the spontanous electron flow is only a by-product which we will use.

Tony,

Thanks for responding. In connecting two of the primaries I was thinking of increasing output. Anyway have you tried the primary wrapped over the secondary? Or have they been just wrapped over the outside of the primary coil?

as to the right handed coil versus left handed, I am speaking to the direction in which you wind the coil, for instance look at your right hand palm facing down fingers away and relaxed, the thumb indicates the direction you wind in and the fingers indicate the wire direction when looping over the form. So in a right handed coil the wire startsby going over the top and to the left.

I asked about this since it seems that your primary was wound opposite or in a left handed manner, i.e. wire wrapped over the top when starting and moving to the right as you go around the form.

I also noticed that the secondary is wound in a right handed manner (this is what the picture shows for the one you made for Stephen I think

Just trying to help understand your design so please feel free to correct anything I may have incorrect.

Hi agentgates,

congratulations in your findings but most of all, congratulations for choosing to publicly share your finding.

Looking forward in seeing more of your results.

Thanks for Sharing

Looks good!  I will be following this with much interest.  Here are a couple of YouTube videos from agentgates' channel:

looks like these are different coil designs, and they light the bulbs for only a second.  If there's a problem with the transistors blowing, I echo the thoughts of some others here:  why not use protection diodes across the fets to block or redirect the bemf?
