By the nature of my project, I am designing 2 power electronic boards that are supposed to have its high power main voltage and ground plane connected together. Can you recommend a type of connector or a connection design that will provide the least stray inductance?
A bank of 8 pins each for power & Gnd like one of these would do it, with 3A (or more) current rating per pin https://www.digikey.com/products/en/connectors-interconnects/rectangular-connectors-headers-male-pins/314?k=male+header&k=&pkeyword=male+header&sv=0&pv1989=0&pv88=26&pv90=2&pv2024=9&pv91=623&sf=1&FV=ffe0013a&quantity=&ColumnSort=-66&page=1&pageSize=25
Select a suitable female socket to mate it with. https://www.digikey.com/products/en/connectors-interconnects/rectangular-connectors-headers-receptacles-female-sockets/315?k=female+header&k=&pkeyword=female+header&sv=0&pv1989=0&pv88=32&pv564=2&pv1790=1&pv2172=i2&sf=1&FV=ffe0013b&quantity=&ColumnSort=0&page=1&stock=1&pageSize=25
