That small TPU we see above is a ferrite toroid wound with some coils and activated by a small magnet placed on the inside rim. This device is very simple and I can't imagine any electronic components used. It most likely is composed of wire and maybe a capacitor the most. We know it makes sounds which we analyzed and determined to be power line harmonics, so it appears to be a high Q resonant receiver much like a wine glass that responds to acoustic vibrations, except this thing responds to AC magnetic fields which would be audible if we had magnetic ears. (the human ear can easily hear a 5 kHz audio tone) Besides the high Q mechanical aspect, the TPUs are also high Q because they use REGENERATION. This is the process of providing positive feedback with sufficient gain to almost self oscillate, but not quite. This allows nulling out the resistive part of a tuned tank circuit to further increase the Q over that of a passively tuned tank circuit. Steven Mark has said that the TPUs are like a "furnace that feeds itself."Keeping these principles in mind can guide one to understand the TPU devices by just looking at them. They are all different which is a fortunate thing for us, because we can compare and contract and determine what’s the common denominator. I have been trying to understand the coil arrangements of some of the TPUs, and how the voltage is induced and with what polarity and how positive FEEDBACK can occur to "feed the furnace" and further amplify the reactive fields so that they can induce more energy to be received from the external AC magnetic fields. So, looking at the common mode choke in the center of the TPU, and how it’s wound, made me realize that the "turbine effect" or rotating magnetic field occurs inside the torroid. The torroid is a critical item of the TPUs. It is a two pole single phase AC motor (induction motor) without the rotor, and it needs a phase imbalance to start to spin the field, which the magnet induces I believe, and perhaps this spinning field also interacts with the physical deformation of the ferrite itself as it resonates acoustically. By tracing the coils I was able to determine that I can create regeneration back to the main antenna loop with the correct phase to feed itself. The impedance mismatch prevents the voltage from driving current backwards against the regenerative voltage, so the buildup of energy is at the correct phase with the external magnetic fields and couples with them and extracts their energy. The more I study Steven Mark’s TPUs, the more I realize he really understood his TPUs because he mentions these key aspects.
1) Turbine effect
2) Tuning to magnetic fields
3) Vibrations and Noise
4) High currents
5) Heat
6) Up-side Down shut off
7) Magnet start up.EM PS, The magnetic vector rotates inside the ferrite torroid, and the wires that come out of the center, or the leads, are playing a critical role unsuspected by any of us. The rotating magnetic field induces a peak voltage when the field is rotated 90 deg to what is shown, and the phasing is exactly what is needed to build up the reactive fields because the other phase delay is due to the inductance of the loop where the current is lagging by 90 so together we get 180 degrees of phase difference and, with the correct polarity connection that can be 0 or 360 deg of phase change or possitive feedback. I did extensive calculations of impedances and reactances and induced voltage and current magnitudes, and it looks pretty good. Read about single phase induction motors and why they can't start: http://openbookproject.net/electricCircuits/AC/AC_13.html#xtocid1540137This is similar to how the TPU functions without the magnet, it can't start spinning the field, and if the field is not spinning inside, it does not provide positive feedback to improve the Q, so the received energy is very low, mili volts!, but once it gets going due to the effect of the permanent magnet biasing the core, things begin to build up and the furnace feeds itself and the fire grows hot!
