Hello friends, today in this video i have made a step-up / boost converter. The inductor in this circuit doesn’t have any feedback winding that is why another transistor have introduced. This circuit is very efficient. One used battery will power a bunch of LEDs for several days until the battery voltage goes below . You can make a night lamp or even a bright white led flasher with this circuit. The output voltage goes around 40V without load.
Components used in this circuit:-
1) Bc337 transistor(NPN)
2)Bc547 transistor(PNP)
3) / 22pf capacitor (Sorry for my mistake in the circuit diagram)
4) 47k resistor
5)Inductor from old CFL circuit
6) Enameled copper wire for coil ( Got from 5W CFL circuit’s transformer)
7)4148 zener diode
8)10uf 35v capacitor
Thanks for watching.
Please like👍👍👍 share and comment.
