I want to Fix pcb, there are some paths that do not fit, then I just give jumper with copper wire, and also I can not install protection card, it is not enough space between pwm card. Below new pdf pcb, please check again mr .silvio

As far as I can see all is ok I did not see the protect card yet but it must not be a complicated one. The traces to the gates seem a bit long though and might get disturbed on high power. You can use a twisted pair of wire from the pwm card to jump to the gates and that way they will be away from high current traces,
If you want good results you must put the driver in front of the mosfets and the paths to the gates must me short and thick as possible.
Take a look at the 3K pdf below see how short is the path to the mosfets, The heat sink can be else where if you want.
The input filter need to be a double one with 2 common mode chokes otherwise there will be a lot of EMI
