Вопрос: По поводу 30 ваттного фонарика, там ты регулируешь частоты низкочастотного генератора?
Akula say: Нет, ребята, там ВЧ импульсы, пачки ВЧ импульсов, они... ну как вам объяснить? надо включить, дело в том, что когда у вас трансформатор при включении входит в низкочастотную амплитуду, у вас там уже автоматически будут формироваться пачки импульсов, то есть, потому что там идёт обратная связь по току, то есть, когда уже светодиоды перенакалились подают сигнал ТЛ генератору, ТЛ генератор выключается, соответственно происходит перенапряжение, там идёт двоичное уменьшение скважности, то есть выключение полностью. Тем более, если вы даташит расмотрите, у меня там на самой схеме отключено плавное регулирование скважности генератора, он либо есть, либо нету, поэтому там формируются пачки импульсов с частотой ферорезонанса. И он автоматически формируется, так как у нас, допустим, конденсатор зарядился до необходимого напряжения, то есть прошла определённая пачка импульсов, ТЛ генератор, он выключил в это время транзистор до тех пор пока конденсатор не зарядиться. Этот цикл формируется низкочастотной амплитуды общего трансформатора, который уже в этот момент входит в резонанс.
Арунас: Ну вообще на счёт этого, на овеюунити форуме долго мучались, пытались понять, как эта обратная связь работает.
Акула: Ну там видишь, какая ерунда получается, ТЛ-ку ставишь вне плавное регулирование скважности, да? по обратной связи, а резкое выключение, либо есть, либо нет сигнала и получается так, ТЛ-ка дозарядила, видит дозаряженный конденсатор, она выключается и это будет происходить циклично. Так как в током трансформаторе уже образовалось амплитуда и она этот цикл начинает автоматически связывать, то есть, тут ТЛ-ка, она по сути дела, она не является, как таковым генератором. Она уже делает всё, что происходит в самом трансформаторе. То есть уже трансформатор начинает рвать цикл включения пачек импульсов и выключения на ТЛ-ке, подавая этим самым ток на светодиоды, отрубая по обратной связи, да? то есть по комаратору, эээ вторично уже дозаряжая конденсатор. То есть давая сигнал на выключение. То есть ТЛ-ка там зависима, она как таковая не формирует ничего, в ней задаётся именно скважность, это - равная феромагнитному резонансу и частота следования импульсов, а цикличность их уже формируется самим трансформатором.
Арунас: там насчёт, следующие два момента. один у тебя (не расслышеное слово) как частота, а второй это принцип, где ты находишь именно для обратной связи насколько я понял, да?
Акула: Да, то есть смотри, по току, когда у нас светодиоды начинают больше тока пропускать, у нас идёт команда на выключение полностью ТЛ-ки.  То же самое, идёт перестраховка по напряжению.
Арунас: Ну я так и понял, спасибо.
Акула: Теперь смотри: у меня третья ножка задействована. Да? там через 22 нанофарада стоят, это для чего сделано? Капратар и пятнадцатый компаратор непосредственно силён (может не такое слово) по напряжению именно со разделителем по первому и второму ключу, вот, это что делает? Это блокирует скважность, там нету плавной регулировки скважности, она там либо есть, либо... Поэтому у нас там ТЛ-ка, надо понимать, она работает пачками.
...
Вопрос: Роман, скажи, конденсатор, накопительный C3 2000 микрофарад, можно его больше ставить по объёму?
Акула: В принципе вот этим конденсатором и формируется та основная переодичность включения, отключения ТЛ-ки. Ну а вторичная, это ток, да? то есть это напряжение на светодиодах. То есть меняя этот конденсатор вы будете менять цикл включения и выключения ТЛ-ки, так как она будет смотреть контроль заряда на рабочем конденсаторе. ... Когда вы включите такую систему, вы увидите с выхода ТЛ-ки, что? что там идут пачки, вот, конкретно длительность их вы отстроите по частоте ферорезонанса. Следование их вы уже будете смотреть на мощность, да? затраты к выходу, то есть количество в пачке сигналов. И вы видите цикличность, что на самом деле, она циклична, она практически 50 на 50 получается, работает-выключилось, работает-выключилось, это как раз и есть управление конденсатора рабочего. ТЛ-ка видит, что конденсатор дозарядился, она выключила, нет сигналов. Пришёл уровень заряда, она включается и вот это начинается циклично идти. А эти циклы, автоматически должны совпасть с низкой частотой уже в трансформаторе сформированной и они начинается... в автоконтроле всё таком получается. То есть, это надо делать, чтобы понять.
That from one conference.

"Question : Regarding the 30 watt flashlight , there you reguliruesh low frequency oscillator frequency ?

Akula say: No, guys , there HF (Hight Frenquency) pulses packs HF 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 it will be heated TL generator , the generator is off TL , respectively overvoltage occurs , there is a binary reduction of duty cycle, 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 overunity long tormented , trying to understand how this feedback works .
Shark : Well there you see what nonsense it turns out, the TL posing outside smooth control of duty cycle, yes? feedback , and a sharp cut-off , or is, or there is no signal and turns , TL 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 , 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 , thereby supplying current to the LEDs , cutting off feedback , yes? ie komaratoru , uh already to be completed charging 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 set - equal feromagnetic resonance and the pulse repetition rate , and their cyclical already formed by the transformer .
Arunas: there about the following two points . you have one ( not hear clear 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 . 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 duty cycle, she's either there or... So we there TL , 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  . 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 , 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 feroresonance . 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 gets running, off, running, off, it is precisely the control capacitor working . TL 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."

So from TL going packs of pulses. 50 precents space, then 50 precent pulses. How many pulses in pack is not critical.

C'mon that's not a human translation.
"Porosity"!?  You should've at least replaced it with "duty cycle"

[MenofFather]

C'mon that's not a human translation.
"Porosity"!?  You should've at least replaced it with "duty cycle"

Yes it is duty cycle. In this citation is many words, who nothing saying or saing same. So from C3 seems depends how many pulses be in one pack. Let say pack frenquency probarly 15-40 kiloherc and not inportant or be 15 kiloherc or 40 kiloherc, that is not critical acording to conference. Only pulses must be ajusted to feroesonance of ferite, but maybe akula himself made some mistake in explanation, maybe important then one capasitor discharging or chargin, then need paste pack of pulses. In one conference he say that all his ciruits corect in other that this circuit not completed or something like this. So maybe simpler be just make generator who sends pack of pulses, were we can ajust pulses duty cycle and and ajust frenquency of pack of pulses (how many pulses be in pack).

"Question: Roman, say, capasitor C3 2000 uF can be biger?
Akula: In principe with that capasitor and is forming that general period turn on and turn of TL generator. And secondary winding is curent, right? that means it is voltage on light emiting diodes. That means, then you change this capasitor, you change cicle turn on and turn off TL generator. Because it looks charge on that working capasitor. ... Then you tur on that system, you see from output TL genrator that from it gose pack of pulses. The duration of it you ajust depending of frenquency feroresonance."


Here other masine translation of translate.ru
"[size=78%]Question: Concerning 30 watt small lamps, there you regulate frequencies of the low-frequency generator?[/size]
Akula say: No, children, there VCh (VCh is HF) impulses, packs of VCh of impulses, they... well as to explain to you? it is necessary to include the matter is that when your transformer at inclusion enters low-frequency amplitude, at you already automatically packs of impulses, that is because there is a feedback on current, that is when already light-emitting diodes heat up give the T signal to the generator, T the generator there will be formed is switched off, respectively there is an overstrain, there is a binary reduction of porosity, that is switching off completely. If you datashet consider, at me there on the scheme smooth regulation of porosity of the generator is disconnected, it or is, or isn't present therefore packs of impulses with a ferroresonance frequency there are formed. And it is automatically formed as at us, let us assume, the condenser was charged up to the necessary tension, that is there passed a certain pack of impulses, T the generator, it switched off at this time the transistor until then while the condenser not to be charged. This cycle is formed the low-frequency amplitude of the general transformer which already at this moment enters a resonance.
Arunas: Well in general into the account of it, on overunity a forum long suffered, tried to understand how this feedback works.
Shark: Well there you see, what nonsense turns out, TL-ku you put out of smooth regulation of porosity, huh? on feedback, and sharp switching off, or is, or there is no signal and it turns out so, the T completed charging, sees the completed charging condenser, it is switched off and it will cyclically occur. As in current the transformer it was already formed amplitude and it this cycle starts connecting automatically, that is, here T, it as a matter of fact, it isn't, as that generator. It already does everything that occurs in the transformer. That is already the transformer starts tearing a cycle of inclusion of packs of impulses and switching off on TL-ke, giving these current on light-emitting diodes, chopping off on feedback, huh? that is on a komarator,  again already completing charging the condenser. That is giving a signal on switching off. That is the T there is dependent, it as that doesn't form anything, in it porosity is set, it is equal to a ferromagnetic resonance and the frequency of following of impulses, and their recurrence is already formed by the transformer.
Arunas: there about, the next two moments. one at you (not the hear clean word) as frequency, and the second is the principle where you find for feedback as far as I understood, huh?
Shark:  Yes, that is look, on current when our light-emitting diodes start more current passing, we have a command for switching off completely TL-ki.  The same, goes reinsurance on tension.

Arunas: Well I and understood, thanks.
Shark:  Now look:  at me the third leg is involved.  Yes?  there through the 22nd nanofarade stand, it for what is made?  Kapratar (can be comparator) and the fifteenth comparator is directly strong (such word) on tension with a divider on the first and second key, here, it can not that does?  It blocks porosity, there is no smooth adjustment of porosity, it there or is, or...  Therefore at us there T, it is necessary to understand, it works with packs.
...
Question:  The novel, tell, the condenser, accumulative C3 2000 microfarads, it is possible to put more it on volume?
Shark: In principle here this condenser also forms that main frequency of inclusion, shutdown TL-ki. Well and secondary, it is current, huh? that is this tension on light-emitting diodes. That is changing this condenser you will change an inclusion and switching off TL-ki cycle as she will watch charge control on the working condenser. ... When you include such system, you will see from exit TL-ki, what? that there are packs, here, specifically them you will build up duration on ferroresonance frequency. Following them you will already watch at power, huh? expenses to an exit, that is quantity in a pack of signals. And you see recurrence that actually, it is cyclic, it nearly 50 on 50 turns out, works-was switched off, works-was switched off, it just and there is a management of the condenser of the worker. The T sees that the condenser was completed charging, it switched off, there are no signals. Charge level came, it joins and here it begins going cyclically. And these cycles, automatically have to coincide with low frequency already in the transformer created and they begins... in autocontrol all such turns out. That is, it should be done to understand."


And I little corect some words TL-ki, TL-ka, TL-ku and T is TL494. That is in () is my comments.

@starcruiser

Thanks for your reply. No the probe X setting are OK at 10X since both probes have that small autodetect pin so the scope sees them OK.

When I connect both probes and grounds to the same frequency generator output, under 10KHz both show almost the same waveform with Channel B slightly off square wave and Channel A is showing a good square wave.

But as I go up in frequency ChA will show 100vpp while ChB is showing maybe 15vpp. But both are on the same signal. When I switch the probes, the same ChB does the same problem so it is not my probes. I checked everything I can but nothing.

My scope is a HP 54645D.

It's kind of starting to piss me off royally since I cannot count on the ChB to make true comparisons. This does not however hinder my experimenting, but just a major main in the but. Especially when I want to make a youtube video to show you guys but the scope is not giving a reliable ChA/Chb comparisons.

From the looks of the screen shots this is a frequency roll off due to a bad input stage. I would check the input stage coupling capacitor as this might be causing the attenuation issue. How does it do on DC? If the issue is AC only I would check the front end for channel 2 for damaged components.

If you look at the screen shots the rise time is what is being affected, this makes me think of a bad capacitor since it cannot keep up with the incoming signal (charging the cap). Open her up and replace the input capacitor, if you have a tester I would pull it and test it. Probably a inexpensive fix.

Hi All!


I have made a new drawing of the solder paths, next i will make a components drawing based on the solder paths drawing.

I have also added the 2 differences in what he changed before and after.

If i missed anything let me know, the dotted lines is what he removed.
