18vDC brushed motor driven by a mosfet controlled by pwm for the intention of having speed control, shouldn't see more than 3amps
the direction is change by reversing polarity via 2 relays
now how and the heck do i add a flyback diode to a bidirectional circuit.
i know i need it whenever i shutoff the motor and with the way i believe mosfets work thats gonna be a lot
I've read online but anything I've found goes over my head, i did read somewhere that i can use a TDS i think is what they called it but essentially is specifically for creating fly-back protection for a bidirectional circuit, i couldn't understand how to go about choosing the correct one.
i also came across a few different diagrams usually replacing the standard flyback diode at the motor with 2 flyback diodes i believe pointed at each-other.
i would rather use diodes but again i don't know and haven't been able to understand the methodology of choosing the correct diodes.
i guess i could go on and on but i think i explained what i need and what i'm trying to do, as well as provided all necessary information needed i hope.
Thanks for any help you have to offer i really appreciate it.
