I'm getting read to wire up my mosfets and I wanted some tips for making sure I don't have too much inductance. The signal path will be up to 6 inches in opposite directions (may be closer to 4 inches each way). This is driving multiple mosfets so I'm putting my driver in the middle and plan to solder a signal wire directly across all the parallel mosfets.
I understand I should probably add small value gate resistors to them all to help prevent HF oscillations, but as far as the wire goes. Would it be best to use a small gauge twisted pair wire and ground one of the conductors at each end and the middle?
Switching frequency is ~20khz. And I'm not going to make some eccentric shape to mount my mosfets they are going on a long copper bar/heatsink, doubling as the current path for all of them as well.
Hope this is enough info.
