Author “Super final version flyback driver,” he said, but not so super stable than other simple flyback driver to control at least 555 UC3844 SMPS control IC is used instead. Flyback MOSFET driver circuit used irfp260, 12:18 ohm resistor connected to the source through the legs made of current limiting.
Attention flyback driver circuit produces high voltage capacitor connection Observe caution + – If you connect the high voltage polarity may be large explosions before running the insured Power Line circuit, protective goggles
