I am designing a PCB layout for my team's high current, high voltage project and am having trouble with choosing my trace width
The circuit is composed of 12 inductors placed in series with short traces connecting them together. We are feeding 10μs pulses at ~300A/1000V at a maximum rate of 10 pulses per second by discharching capacitor banks into the coils. The capacitors are recharged by an external source.
As determining trace width for very high current pulses, is there a rule?
