I've searched for some answers to my questions, but I haven't been able to find a thread that directly answers the questions I have.
I'm trying to design an H-Bridge to interface our microprocessor to our 24v DC motors. The plan thus far is to use optocouplers between the processor and the FETs to isolate the processor and amplify the PWM signal. However, is this the best route? Or should I be looking at using a MOSFET driver?
Do I need to use both N-Channel and P-Channel FETs? The diagrams I have seen don't seem to be consistent as to whether 4 N-channel FETs can be used or if I need both types of transistors.
Do I need to create a differential (+12/-12v) source to run the bridge? Or straight up 24v and ground? Or does it matter?
Thank you in advance, I know that's alot of questions.
