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.
