    I am planing to use Atmega 16 to make a controller that controls the DC 35 Hp motor .Any any one has done?
    that would be a great help.
    Motor will be used for electric car
    My Idea is that generate PWM and use Mosfets after that and control motor .Will this work and do I have to use Mosfet drivers before Mosfets or using Microcontroller->NPN ->PNP ->controling mosfets

    will help?

    Can you clarify your title? Is the motor you are using a BRUSHLESS DC motor, or simply a DC motor? It makes quite a bit of difference in the complexity of the drive.

    so far I plan to use BLDC motor and I think that will be better for electric car

    A brush type DC motor can be controlled by PWM of the power feeding it. (We won't even go into dynamic braking, etc as applied to an electric car) A BRUSHLESS DC motor requires much more sophisticated control in which to accomplish commutation of the typical 3 phases. There is a wealth of information on the web about BLDC control.
