I finally got to put my homebrew controller together.
The bench tests look good using an industrial linear actuator.
Looking forward to do some testing on board.
Sourcing the right parts in small quantities was not easy in my country. ( NL)
So below is what I could find and used, might be useful for somebody.
I used IRFZ44N MOSFETS with IR2110 drivers.
For the MUR160 diodes I used SB260 Schottky diodes
I used a 14,4V 1500W TVS diode on the motor and 17 V on the 12V supply.
The 4,7uF foil caps are 400V and a bit bulky
Could not find a fast optocoupler, but did use a 4 channel level converter module.
Everything is on an 8x12 cm prototype board including Fuse holder, shunt, a Nano clone, 5V DC/DC converter and level shifter.
Used solid 1mm wire for the H bridge.
