Just place capacitor after diode and attach analog milliampmeter to show power consumption as your PS amp meter is not that sensitive for mili/micro amps draw ;)

Если я это сделаю то измениться LC параметр, а следовательно и уйдет резонанс.
Убрать потребление на данном этапе  не есть моя цель!!!
Моя цель максимально намагничивать сердечник для съемной катушки.
The tuning must be with all  parts connected including constant load so the resonance won't go away. The freewheeling LC circuit will be always affected in any change of transformer core magnetization which will change inductance of all coils with each try to take energy out of it even if it gets maximum saturation of core when there is no load attached to transformer.

When your PSU is showing the higher voltage and zero current.... please then vary the output amplitude of the Function Generator to see if this PSU-indicated voltage changes.

The meters on the Power Supply should _never_ be used to make quantitative calculations or claims. They are just there so you can set the PSU easily. You should always use separate meters connected properly to your DUT to make quantitative measurements. As I've shown the voltage indication may be subject to false indications due to the circuit's voltage actually supplying more than the PSU is set for (and other reasons), and as you note the current indication is only good to two significant digits and is only approximate.

Вот так использую конфликт токов получил уже что то в резонансе.

Google translates that as:

Quote
here so use current conflict has already received something in the resonance.

Which isn't any language I understand.

The purpose of communication is to transfer information effectively, isn't it? This forum has sections in French, but mostly it is conducted in English, even though it is based in Germany and our host is German.  If you want to start a Russian section, you can probably do that easily enough. I won't be reading there, so that might be seen as a benefit to you.

"So I am using conflict of currents(EMF against BEMF) and got something in resonance"


Obviously you cannot push Russians to speak proper English when it comes to specific terms and Russian experimenter with fluent English is rare find ;)

hi semenihin-77,

Please do use www.freetranslation.com to convert Russian to English.

Пожалуйста используйте www.freetranslation.com для преобразования российской на английском языке

--------------
My findings this translation site offer little better grammatical correction as compared to google translate.Everyone please do try out.

I do understand your frustration. However, I must say that I have received a wealth of very useful information from some members here.
Since this is an open forum you have a very diverse community. From complete newbies to real scientists to utter dilettantes posting non-stop without real commitment to knowledge.

Perfect it is not, but whatever the formula is - it's definitely working in my case. Semenihin-77 has shared some very valuable information with us and I am, for one, grateful. He brings new angles and ideas instead of trying to dazzle us with his skills and knowledge as many members here do. I sure hope that he stays and would be happy to communicate in any language of his choice.

I prefer to have Russians here speaking Russian then to not have them here at all.
Like above, I've gain a tremendous amount of new information from Russians over the years.
Google translate isn't perfect but it's better then anything else I've tried.
 
My only request to the Russian speaking people is to please spell the words correctly in Russian so Google translate will have a chance to translate it.

Thank you,
DonL

I might be in the wrong thread here but their is a lot of frustration about. but could I just give you all this thought. Can I just ask how you have wound the transformer as the akula foto shows half the bobbin primary going one way on one side and the other half you can't see as it's under the secondary, but is it wound in the opposite direction ? could it be that simple ?

Полная схема в начале ветки, с печатной платой.

Уважаемый semenihin-77,
какая схема из трех, приведенных в первом посте, у Вас лучше всего заработала?
