A little while ago I was building a circuit in order to replicate Clemente Figuera's transformer. Rather than build a current supply in the same style as Figuera, which is a little complicated and likely a little lossy, I thought it would be simpler to use the 240v 50hz house supply.
The house supply is of course, single phase. I somehow needed to achieve a supply of two anti-phase currents from this single phase. The solution was to build a transformer with two identical secondaries and supply each of the Figuera primaries from opposite poles of those secondaries.
Figuera described climbing and falling sines in his patent so I imagined he was earthing his supply battery, thereby causing his sine waves to bottom out at 0 voltage.. But was he, and does it really matter?
While I was considering this I noticed something that was in fact obvious, to anyone but myself I imagine
The transformer was in and of itself a replication of Figuera's transformer, only in reverse. I wondered what would happen if I simply connected a load between my two secondaries. I went to https://www.falstad.com/circuit/index.html and modeled my transformer with the load between the secondaries.
It was not possible to model a single primary with two secondaries as I required so I connected two transformers in series, each with a single secondary. I put the load in series between those secondaries and was quite surprised at what it showed. If I had more experience, perhaps I would not have been.
Although the simulator is not altogether accurate is some respects, what I saw was, for me, very interesting and not a little confusing. I shall upload a circuit diagram for everyone's perusal.
I welcome everyone's observations and criticism. Please be kind though. I can be an idiot at times.
I do have a few questions about this that forum members may be able to answer for me.
Apparently my file didn't upload so I will try to add it again.
