do you know, I want to achieve only illumination of the lamp at full power at 1% duty cycle, please help me!, I know that it is possible
it is very important for my project

Hi x_name41. I thought you were trying to show us some unusual effect?
When doing these sort of tests you really have to monitor the input current from the power
supply closely, otherwise you can't tell if anything unusual is going on.

I tried a test setup with your schematic posted at:
http://f-picture.net/lfp/s008.radikal.ru/i303/1604/da/016b56a0e084.jpg/htm
This arrangement is not working for me. When I briefly touch a wire from the cathode of the 1N4007
diode to the drain on the switching MOSFET, my light bulb goes dimmer. I do get some big
switching pulses from my choke, but this arrangement is not making the bulb get brighter for me.
Can you confirm that your schematic at the link I posted above does not have any errors in it?

everything is right Try to switch in different ways manualy and will appear effect

The behavior of this arrangement would be highly dependent on the parameters of the MOSFET such as V_{GS_th} and C_GD and C_GS C_iss.
Also your diodes and the gate driving device might be different than his.

Thanks Verpies. Yes, I did now get it to work like x_name41 showed in his video, but the
input current draw from the power supply increases in proportion to the brightness of the bulb.
I think there is nothing unexpected happening in this circuit setup, at least based on my own test.

I only had two different types of schottky diodes to choose from, one with a 100V reverse breakdown
and one with a 40V reverse breakdown. When I switched to the 40V reverse breakdown schottky diode it started
working like x_name41 showed with the bulb getting a lot brighter when the cathode of the choke diode is connected
to the drain of the MOSFET. However, in my setup I did not see any advantage to just briefly connecting the
choke  diode's cathode to the MOSFET drain, at least not so far.  If I leave it continually connected, the bulb stays bright,
as might be expected, and the input current draw from the power supply is quite a bit higher in proportion to the brightness
of the bulb.



@T-1000: Ok on the meaning of 'гравицапы'. No wonder I couldn't figure out what it meant.
