if I take 0,1uF/400V capacitor good for high frequency circuits polyester type and join both terminals with a fast diode for 400V what I obtain ? Is that now polarized capacitor like electrolytic one  and can be charged only using DC and used only in DC related circuits ?   

Yes, but not only in DC or DC related circuits but in pulsed circuits where the polarity of the pulse mainly have a single polarity and little opposite polarity (on opposite I mean the polarity where the parallel diode would conduct (would become forward biased) and would clamp that polarity to its forward voltage level, say  .7V).
For AC waveforms with zero crossings like a normal sinusoidal voltage your cap + diode combination would short circuit that half wave of the AC wave which would forward bias the diode, the other half of of the AC wave can charge up the cap to its peak amplitude.  Remember: when the diode conducts in its forward direction, a huge current can go through on it and this current is only limited by the AC voltage source inner resistance or impedance and whatever component(s) are in series with the AC source towards the diode.

I am not sure what exactly you mean on computing current properties in saturated inductors?

I begun sto study Tito's suggested patents starting with 568.178 one. Similar in concept to the Ozone patent.

The basic principle of operation as Tesla notes, is charging a high self indcution coil, then upon circuit break, coil collapses in a capacitor, bringing it to high voltage, then upon circuit reconnect, capacitor discharges in a LOW induction coil, which have a recepient secondary coil which depends on our goal.

I liked this patent's full features of control as, adjustbale high self-induction (or adjustable L/R ratio) for regulating power strength of apparatus (same with a rehostat) thus adjusting motor speed, adjustable commutator's brushes, adjustable primary inductunce and secondary. All adjustable.

Whereas, adjustable primary's LpCp or secondary's LsCs parameters are for attaining best resonance match, the adjustable motor speed and brushes are for propar pulse phasing!

I explain. In the energetic forum

I am comparing my experimental results between a Kacher or Solid State Tesla coil and a traditional shock-excitation Tesla coil.
The solid state, have a perfect resonance effect, smooth as i say and bring FL tubes to full brightness next to it (the proof). On the contrary my traditional spark-gap Tesla coil that pulses some 100 times/sec, has not any smooth resonance effect (fails to light a neon to a satisfactory brightness or a FL tube to any particular brightness) yet its sparks and general behaviour is vast more energetic than the solid state one.

I concluded in resonance grounds that the traditional spark-gaps sux, because they cannot guarantee us that they fire in exact same time intervals, thus one can be in contrast to another due to wrong phasing even though primary-secondary resonance's parameters are the same. I acknowledge in large Tesla coils that can light a FL to tens feets away, full brightness even thought they may appear perfect resonators in fact they may not be. A o-scope can tell as always about it.

Anyway, that was a observation of mine.

Btw i am far more interested at the moment in shock-pulsing than smooth resonance, because i see the far more energetic nature of shock excitation.

I was not useful lately so I found Tito first schematic and added polarity marks 
Keep going.

Polarity marks are of course based on diode direction

he he I have already about 10 relay circuits to test based on this Tito schematic
Maybe I catch the one and only 
May I ask if diode and resistor goes always across capacitor terminals ? I'm preparing a common "blocks" to play with that around relay and I'd like to merge capacitor,resistor and diode as one "block".
Let's play!
