Keywords: Bipolar Stepper Motor H-bridge.png This is really not a good circuit With higher power supply voltages both mosfets on a side can be turned on at the same time resulting in a short across power supply The gates to upper lower mosfets of a pair need to be controlled so they don't turn on at the same time Level shifters should be used --Aflafla1 <span class signature-talk >talk</span> 00 12 24 May 2012 UTC Diagram of an h-bridge driver for a bipolar stepper motor own Own Drawing 2006-09-27 inductiveload PD Stepper motor drivers H-bridge circuits |
