This section is a work in progress - I am still learning and as we continue to experiment, we continue to learn.
We want to have Electromagnetic Induction occurring more than once in a System, An A-Symmetrical System
What to look for:
Several times I have seen the same problem, some people even report: "I am only getting Transformer Efficiency's"!
Most of the time, the reason for this is simply, that: The Magnetic Fields, the Currents, are not in Opposition to each other!
This is irrespective of the Winding Geometry's or Configurations! Fields must oppose no matter what!
A Transformer is based on Electromagnetic Induction, which is the Time Rate of Change of the Magnetic Field in the Proximity of the Conductor:
E.M.F = - N dΦB / dt
E.M.F is the potential difference in charge between two terminals of the "Generating" Coil.
Negative Sign (-) is Lenz's Law, an equal opposite Magnetic Force from the "Generating" Coil reflected back on the Source Magnetic Field.
Number of Turns (N) is the Number of Turns on the "Generating" Coil.
dΦB is the Variance of the Magnetic Field B. Min to Max Field.
dt is the Change in Time (t).
Transformers, Transform, Voltage and Current, there is Electromagnetic Induction occurring only Once in this Symmetrical System! We can either Step up or down these units, one being the inverse to the other. Meaning, to step up Voltage, Current is stepped down and vice versa.
Transformers aside, in our devices, depending on your configuration, the Input Current becomes the Output Current, less losses, all Systems have Losses, and there is not sufficient Electromagnetic Induction to make a difference to the System! Thus the statement:"I am only getting Transformer Efficiency's"
Sometimes Magnetic Fields don't Oppose?
In our configurations, it is the case that sometimes the Currents don't oppose. This is a very odd problem!
It is the case that the Input Current is greater than the amount of Electromagnetic Induction between the Partnered Output Coils! This is quite common! Personally I have not seen this very often, and I will explain why I believe this is so.
As stated above, the Magnetic Field and the Change of it in the Proximity of a Conductor (Coil), is the requirement for Electromagnetic Induction. Turns (N) also being part of the equation. Also, the Magnetic Field B is deemed a quantity that is dependant on the Turns (N) the Current (I) and Length (l (small L)), the equation takes this format:
B = µ0 N I / L
B is the Magnetic Field in Gauss
µ0 is the Permeability
N is the Number of Turns
I is the Current
L is the Length of the Coil
It is interesting to note the old term "Ampere Turns" (AT) is AT = NI
When the Magnetic Field (B) is not sufficient to Induce a E.M.F in the Opposing Coil, then the Current we put into the Circuit will become the dominant Current.
There will not be enough Electromagnetic Induction occurring in the System to Invoke Opposing Magnetic Fields!
The cause of this can be twofold:
- Not enough Current flowing through the Coils!
- Not enough Magnetic Field!
Because this is a Chicken of the Egg scenario, we have to look at solving this problem from a few angles.
- Increase the Current flowing.
- Increase the Turns on the Coils and keep the Current the same.
Because the Turns are a quantity in the above equation, and by keeping the Current the same, we get more Magnetic Field as a result! This also increases the Electromagnetic Induction occurring.
Some Cores are Slugs! I have tried a few cores and they just don't want to play nice! So trying another core may help sometimes!
I am not sure 100% here, so this section could change at any time also.
If an Antenna is not matched for a particular Radio, the Signal will reflect and the Radio will not receive as much signal as it should! The radio can be damaged as a result!
I believe this is part of the reason we often look at the 1/4 Turns ratio!
How to Check:
I monitor my Currents with Two Current Sensing Resistors:
So, I guess, first step is to ensure you have Currents flowing in Opposite directions, Magnetic Fields must Oppose! Thus the importance of the MrPreva Experiment! There is a little fiddling, so stick with it! Don't give up!
Please keep checking this post to check for changes.
