1.5Volt to 35Volt 1Ah Make Easy.
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 1.5V battery will power a bunch of LEDs for several days until the battery voltage goes below 0.6V. 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)0.022nf / 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
How to make easy Converter from 1.5V to 5V DC for USB Charger circuit smart phone
Component:
- 2 Transistor NPN 2N2222
- 4 Resistance 680 ohm=2 and 22 ohm = 1 and 1k=1
- 1 Regulator IC LM 7805
- 1 LED
