I am designing a board with 15 to 20 parallel mosfets. I need some ideas on how to design this board with the ability to flow 600-800 amps of current at 100-144 volts. I'm pretty sure no board I could etch would be able to supply even 100amps. So I'm trying to think of a way to design a board where I could bolt on a copper buss bar right next to the mosfets to carry the high current and still allow the mosfets access to the heat sink. Or solder individual large wires right near each mosfet and run those to a bus bar.
Any ideas would be helpful.
The mosfets are 200v 65amp mosfets with 15 to 20 in parallel, with a high current driver circuit and switching frequency of 25-30khz. Average load per mosfet not expected to be more then 170v at 20A, with peak of 50A for less then a few seconds happening very seldom.
