Well yes, you need MOSFET drivers, and all MOSFET driver chips assume MOSFETs with 12V or so gatedrive, yet you have logic level MOSFETs with an absolute max Vgs of 12V, so they cannot work from standard MOSFET drivers.Look at the datasheets for chips like IRS2001, FAN7380, HIP4081 to see how its done.At these power levels I would not trust to driving direct from a logic signal as the drain-gatecapacitance could easily overcome your logic output and blow up the logic chip on transients.Furthermore without high-low MOSFET driver its hard to drive the top-side switches easily.[ What you are attempting is fraught with issues, such bridges will simply pop MOSFETs ifanything goes wrong, protection circuitry is important and MOSFET drivers give a first levelof defence - high power brings high risk ]
It may look stupid, but as a beginner, I would had love to find a post like this at the first place and I'm sure I'm not the only one in my situation.
If you don't have an oscilloscope and a good current-limited bench power supply you are not equiped to tackle such a project really...
I found this online and I think that I will try it for fun. But I have a small concern:When one side is power up (INPA, INPB) and the mosfet and turning close or open. Is there a small moment where both mosfet will be partially open and so creating a short? How much time does it take to a mosfet (p and N) to completely open or close.
