Furthermore, what's the point of drawing a schematic with no component values?
Same here...I completely fail to see the purpose of this circuit:
You need to provide component values. R2-4 form a voltage divider. Without knowing their values and the part number for D1, I can't determine the voltage across R1. As connected, T1 is nothing more than a capacitor.Component values are important but not in this case. I just want to know how this circuit works and what is his purpose.
I have tested this circuit on breadboard and first I have connected 100VDC without any voltage between drain and source and then I had Vgs=18V. But when I connected voltage between D and S (30V) I lost the voltage Vgs.
It's your negative voltage regulator. Can't say more because you didn't provide part numbers for the regulators or values for the resistors.Second thing....rectifier diodes (D9, D10) are connected also to the ground and from there to input from voltage regulator ?....sorry but I have seen first time circuit like this one.

Mhhh... I'm only willing to play this game with you because I think I'm going to learn something valuable.I'm late to the party:
A negative power supply is a good source of electrons.
What does a positive power supply source?
Thank you very much dl324...The first schematic is an inrush limiter; perhaps because C3 is large or the load draws high current at startup. T8 seems to be wired incorrectly because the body diode will be forward biased with just a few 10's of mA of current at startup.
The second schematic is incomplete.
There are no gate connections to T3 and T4. I assume the component labeled Trafo is a transformer; if that's the case, it would help to know how the other windings are connected. Are L1 and L2 really inductors or are they part of a transformer? The part number for D11 doesn't help identify it's purpose (a catch diode?).Second schematic I made and checked 100 times. I can not understand. What do you think, where have I make a mistake. There are no other connections whit a gate or source of mosfet T2 (maybe I missed something but I believe I didn't because I checked really many times). And RLC circuit between gate and source of mosfet?
What is missing?

My guess is that the circuit is a DC-DC converter.
It's okay to ask questions on this forum. Even people who know, or seem to know, a lot can learn more. Someone asked for help with a waveform slope detector. I had never designed or analyzed a circuit for that and I learned something in the process.
