DC/DC Step-up Converter using 555 timer | 5V to 16V

[EllinonEnosis]

Δέν ξέρω άν θα προξενηθεί πρόβλημα στα ηλεκτρονικά γιαυτό. Θέλω να βάλω μιά 12βόλτ 7-19Α μπαταρία και να βάλω ένα μετατροπέα απο τα 12 στα 48βόλτ.

Φίλε ένα τέτοιος μετατροπέας θα μπορούσε να χρησιμοποιηθεί σε μιά ηλεκτρική DC motor ? GoldenMotor για ηλεκτρικό ποδήλατο ?

how much current it can handle?

actually you cant use 555 timer because the "D" is not change at all.. so we must use PWM (pulse width modulation)

[amir89hamzah]

so can you tell me.. it is the rotation speed of the fan increase??

i dont understand the concept of the negative feedback, i assume that as you mean reduces the duty cycle. the self timing is the reset pin's voltage dropping to zero as the inductor is saturate. you can explain more to me, i was thinking of how to make a variable power supply running on a rechargeable battery. Something you should add is current volatge regulation

THNX :)

the next step is a 12 to 220V using 555.

@atheatos Φτιάξε βρε έναν αντιστροφέα :) :)

awesome !!!
