Static High-Voltage Mishin/Tesla Coil. Connection Methods + Effect Never Described Before

A year ago Alexander Mishin presented the second, recommended for health improvement, type of coils, in particular, a static high-voltage induction coil (as distinct from the first one – capacitive coil).

If the first type (capacitive) coil is current-fed (when at resonance the coil current is at its maximum, while the input voltage is vice versa, minimum), then to feed the static coil one needs to apply a high-potential resonant frequency there (through one conductor). This coil differs from the capacitive one in that it generates a powerful electrostatic field, therewith, the electromagnetic component remains minimum.

In this case the electrostatics is as powerful as, with the voltage applied slightly over the specified threshold, the “smart devices” nearby such as computers, graphic tablets and smartphones begin even to “run mad” — panels (boxes) fly on the screen, texts are keyed-in at random, mouse malfunctions and the computer may either shut down or re-start…

The high-voltage, static coil requires that a high-voltage (potential of some 150V by one conductor) should be applied thereto at the coil resonant frequency, with the current remaining in this case next to nothing. Obtaining this kind of voltage from a transistor-type generator is rather problematic, therefore use is normally made of a step-up transformer. Two, relatively simple variants are generally used to this effect.

1. as a step-up transformer make use of a capacitive, bifilar-wound tore (twisted pair) — to remove a high potential from one of the free ends of the bifilar half-winding, therewith, the resonant frequencies of the static coil and step-up capacitive tore MUST coincide (the error is not in excess of 1kHz, otherwise effectiveness will decline most steeply), In this situation the tore totally determines the frequency of self-excited generator;

2. as a step-up transformer make use of a wide-band transformer based on a small-sized ring core of ferrite. In this case the generator frequency must be set forcibly (manually).

Both variants have their advantages and disadvantages.

Resonant capacitive step-up tore.

Advantages:

a) User is not required to manipulate with the AFC (automatic frequency control) generator, as the capacitive tore dictates the frequency – once connected,- may be used. As a matter of fact, this is where all advantages come to an end, as for the rest – just nothing, but shortcomings alone;

b) exceptionally a not easy-to-manufacture product, therefore its price is rather high;

c) relatively large overall dimensions;

d) precision of capacitive tore tuning to resonance with the static coil is expressly declared, however, to achieve this in reality is exceptionally difficult (it is adjusted by winding off the initially wound on excessive turns, after which the winding must be fixed properly, however, any tore-involving manipulations, tightening, especially, will automatically result in a frequency drift, therefore the human factor is not to be neglected at this moment).

e) common user is practically unable to check for precision of «tore + static coil» pair tuning to resonance, what is left for him to do is just to rely on the Manufacturers’ honesty and happy circumstances.

f) as distinct from a capacitive coil, the static coil is highly sensitive to appearance of any additional capacitance (the coil is placed on one’s body or, for instance, one happens to sit upon it) – its resonance falls immediately by some 5-15 kHz. In this situation the effectiveness of coil declines steeply, unless generator frequency is adjusted, (while the frequency of self-excited generator is dictated by the step-up tore, which is quite irresponsive to any change of the resonant frequency of the static coil). For this reason including, Alexander Mishin advises the Users to avoid placing the coil on the body, but just to put it down nearby.

Wide-band step-up transformer based on ferrite ring core

Here we shall begin with the shortcomings:

a) it must be possible for the generator in use to dictate the wanted frequency forcibly (manually);

b) as follows from the previous item — the User will be required to resort to additional manipulations for the generator to go over to the required mode of operation (in case it is possible) and to dictate the frequency forcibly.

Advantages:

a) production process is not relatively complicated, consequently, the cost of a small-power transformer is many times less than that of a capacitive tore tuned to a particular frequency;

b) complete set (at the expense of the ferrite ring core used);

c) one does not need to rely on the Manufacturer’s honesty, — at any moment one can check and update carefully the precision of generator tuning to resonance with the coil;

d) static, high-voltage Tesla coil may be used not only when it lies aside, but also when placed on one’s body or when one is sitting upon it – resonant frequency drift down by (5-15 kHz) may be checked and compensated for at all times by changing the generator frequency.

Attention! There has been detected an entirely unidentified previously moment in the process of static coils use. When at resonance, a coil lying aside consumes an extremely small current, therefore an AFC generator does not “see it” and cannot monitor the resonant frequency. However, if the coil is noticeably loaded (for instance, one sits upon it), then, firstly, as was previously mentioned, the resonant frequency drifts down steeply by (5-15 kHz) and, secondly, the coil-consumed current rises sharply (if the resonant frequency is ensured), sometimes (depends on electrical quality factor of the coil), so that the AFC generator begins to “see” the coil resonant frequency and, what is more important, starts to monitor this frequency.It must be understood, that as soon as the load is removed (one’s behind from the coil) – the generator AFC system falls out of resonance immediately, and for the operation to be continued it is necessary to switch off the generator, sit down again and switch on the generator. This effect was tested with the «Live Sinus 5» generators, however, it should be noted that not all coils permitted the use of AFC in this kind of application. There were found some coils, that the generator failed to see in principle! Probably, the electrical quality of those coils was a little below a certain threshold value.

As already known to many people, the «Live Sinus» makes use of the static, high-voltage Mishin/Tesla coil exactly with a wide-band, step-up transformer (based on a ferrite ring core) in the form of a small-sized additional adapter, delivered complete with the static coil. To ensure performance with this kind of coil used the generator must be either switched over via an external application to the so-called «Engineer Mode», or the required frequency must be set manually. One may also try to use another variant – when in the standard mode of operation (with automatic frequency control) – load the coil with one’s behind!
