Hello Is anybody has experimented an big power interface with a PIC ? I would like to make a speed variator for a 12V CC motor. The maximum current is 80 amp. I like the schema provided by 4QD http://www.4qd.co.uk/ccts/pwm.html with regenerative braking for automotive equipment. I believe that it is necessary to use a voltage doubler (Vgs > Vds ) to drive efficiently a power mosfet with a 16C84 port. What some do you think ? Regards Robert Rivoir
