I am trying to assemble a simulated Boost converter PFC on dot PCB.
I am having trouble selecting the connecting wires to be used between components.
The peak current can go up to 30 Amps (Power rating around 3kW) with high-frequency switching up to 100kHz.

I first thought of using solid AWG 6 wire but it will limit the flexibility.
Also considering the skin effect it sounds like a poor choice.

Will normal stranded wire do the job for this application? (although the strands are not insulated)
Or do I have to strictly consider using Litz Wire strictly?

Regards,

 

The current is not so simple.
It is not all high frequency current, for which the skin effect will be important.
A large proportion of it is DC current, and there also a 100Hz component for which the skin depth will be huge, so can be ignored.
Work out how large the 100kHz component of the current really is, and the heating that will result from the greater wire resistance due to the skin effect and you may find that solid core (or stranded wire with no insulation between the strands) may suffice.

 

Thanks for the reply Ian.
Yes, the line frequency component can be ignored.
But can you clarify more on : " Work out how large the 100kHz component of the current really is, and the heating that will result from the greater wire resistance due to the skin effect "

 

If you are modelling it in SPICE, do an FFT.
If not, find the peak to peak ripple current and divide by 2√3 to get the rms value.

 

Regular stranded wire will heat up just like solid wire.

For stuff like this I suggest trying multiple strands of enamel insulated magnet wire. You can also buy Litz wire in various sizes
