i am trying to make an ignition coil driver based on the attached schematic. The picture shows the wrong polarity. i am trying to substitute a mosfet for a bipolar transisor in the hope of getting a little more output because of lower internal resistance. SgtWookie kindly showed me how to calculate the gate resistor. http://forum.allaboutcircuits.com/showthread.php?t=39677
im having no luck with this. when i use an irfp250 i get next to no output. am i doing something wrong or do i just have the wrong idea to begin with?? thank you much!!
