A simple converter for powering energy-saving lamps

I would like to present to your attention a simple converter for powering fluorescent fluorescent lamps or energy-saving lamps. The circuit is built on the basis of a single-cycle blocking generator and consists of only six parts.


The transformer is wound on a W-shaped core. The ideal option is a transformer from a Soviet-made telephone set. The lamp winding is wound with a wire of 0.1 - 0.2 mm for an 11 Watt lamp of 200-250 turns. Then the collector winding is wound and contains 20-30 turns of wire 0.35 - 0.6 mm. Next is the base winding - 5 - 7 turns of any wire.
Resistor R1 is selected when setting the current consumption in the range of 0.6 A - 0.8 A for an 11 Watt lamp.
In general, the circuit works immediately without adjustment; if not, then change the wires of the base or collector winding.
Personally, I bought an 11-watt lamp in the store. I disassembled its starting circuit (otherwise it won’t work!) and powered my assembled converter from a 6-volt battery. See photo:
 


The brightness is decent - excellent!


Heating of the lamp and transformer is allowed.The transistor must be placed on the radiator.

    I assembled, connected, measured the voltage at the output, 140 volts, connected the lamp does not work sadsadsadsad
    measured the voltage -0 angryangryangryangryangry
    what's the matter

    What is the current consumption?!

    That's impossible. send a photo of your installation.

    Understood! The transformer core is made of iron, but it should be made of ferrite! Well, so black!

    Here is my creation of a battery-powered blocking generator.

    Works great! consumes 0.7 A from 3.8 volts!

    Cool from 3.8V, can you describe how you did it and twist the coil yourself or rip it out somewhere?

    Just as written above, only the collector winding has five fewer turns.
