Dear All.
I have just put this statement in Russian through Goggle translate.

Question : Regarding the 30 watt flashlight , there you reguliruesh low frequency oscillator frequency ?
Akula say: No, guys , there rf pulses packs RF pulses , they ... well, how do you explain that? should be included , the fact is that when you have a transformer when the low-frequency part of the amplitude , you already there will be generated automatically burst , that is because there is a current feedback , ie , when it is fed a signal LEDs perenakalilis TL generator , the generator is off TL , respectively overvoltage occurs , there is a binary reduction of porosity , ie, switching off completely. Especially, if you examine the datasheet , I got off on the scheme itself smooth control duty cycle generator , it either is or is not present, so there is formed with a frequency burst ferorezonansa . And he is automatically generated , since we , for example, capacitor is charged to the required voltage that is held fixed burst , TL generator , he turned off at this time of the transistor until the capacitor is not charged . This cycle is formed by the low-frequency amplitude common transformer, which has at this moment is in resonance .
Arunas : Well, actually about that on our forum oveyuuniti long tormented , trying to understand how this feedback works .
Shark : Well there you see what nonsense it turns out, the TL -ku posing outside smooth control of porosity , huh? feedback , and a sharp cut-off , or is, or there is no signal and turns , T -ka then charged , the capacitor sees recharged , it shuts down and it will happen in cycles. Since the torus transformer already formed the amplitude and the cycle starts it automatically link , ie , here TL -ka , it in fact it is not , such as a generator. It already does everything that happens in the transformer. That means that the transformer starts to tear cycle the bursts and off for TL -ke , thereby supplying current to the LEDs , cutting off feedback , huh? ie komaratoru , uh already dozaryazhaya second capacitor . That is giving a signal to the shutdown. That is, there TL Single dependent, as such, it does not generate anything , it is the duty cycle zadaetsya it - equal feromagnitnomu resonance and the pulse repetition rate , and their cyclical already formed by the transformer .
Arunas there about the following two points . you have one ( nerazslyshanoe word) as the frequency, and the second is the principle of where you find it for feedback as I understand it , yes ?
Shark : Yeah, I mean look at the current, when we have more current LEDs begin to miss , we go off on a team full TL -ki . The same goes reinsurance voltage .
Arunas : Well, I never understood , thank you.
Shark : Now look : I have a third leg is involved . Yes ? there are over 22 Nanofarad is what has been done? Kapratar and fifteenth comparator directly strong (maybe not such a word ) is the voltage divider with the first and second key , so it does what? This blocks the duty cycle , there no smooth adjustment of porosity , she's either there or ... So we there TL -ka, must be understood. it works in batches .
...
Question : Roman , say , the capacitor C3 cumulative 2000 microfarads , you can put it more volume ?
Shark : In principle, it 's a capacitor is formed and that the main Periodicity enable, disable, TL -ki . Well, while the secondary is current , right? ie . this stress on the LEDs. That is changing this capacitor you change the cycle on and off TL -ki , as it will look on your charge control capacitor. ... When you turn on a system , you will see output tlki that ? there are tutus , here , specifically the duration you can rebuild their frequency ferorezonansa . Following them you'll be looking at the power , yes , the cost to the output , ie the number of signals in a pack . And you can see the cyclical , that actually , it is cyclic , it is almost 50 to 50 poluchaetsya running off, running off, it is precisely the control capacitor working . TL -ka sees capacitor re-charge , she turned off , no signals . Came the charge , it is included here , and it starts to go in cycles . And this cycle will automatically be matched with low frequency transformer already formed and they begin to auto control all this turns out. That is, it must be done to understand.

I think this might have a bearing on our replication efforts??
Cheers Grum.
