As part of a group project I have been given the task of building a H-Bridge circuit to replace a previously built one in a fighting robot. I have no access to what this H-Bridge looked like or what transistors where used etc. I understand only the basics of a H-Bridge about how it works and what type of transistors I will need to make it work. Since the motors that need to be driven are high powered (dc motors and do not know any specs but can find out) I am struggling to decide on a circuit design. I have found multiple circuit designs online where some use diodes and capacitors and others don't. What I do know is that the transistors I need to use are MOSFETS (both npn and pnp) that need to be around 60V/70A. The input signals will come from a pwm speed controller. I have been advised to look into using a H-Bridge driver chip as well but I don't know where this could be connected in a circuit I design or find. I just need a bit of a push and help on where to begin and why. This is one of the circuits I have been looking at and wondered if I changed the transistors for more powerful MOSFET ones I have ordered whether it will work the same or not for what I need. If there is any more information that I would need to provide I will gladly be able to find out and all comments and inputs will be appreciated greatly!!
