H-bridge Help!!

goblin_techies · Dec 22, 2006

hi, just wanna know if i can build a h-bridge by using four NPN transistors??
i want to control a bipolar stepper motor using them

No you can not.

how about 8 NPN transistors? and some diodes and resistors?
i mean, can i make an h-bridge without using PNP transistors to control a stepper motor?

No!
A stepper motor is not a regular electric motor.

i know, i know...im trying to control a bi-polar one

You need to switch power to the the windings in the correct sequence = no H-bridge.
