Simulators Practice

Check yourself!

With demo data examples (jjexamples.zip) you can check your basic engineering skills. Using those data, you can recreate demo example. Simply use your open mind but remember to get identical charts you have to enter parasitic (LSR and CSR) parameters:

For LOW section:

0.37Ω for LSR1A
0.01Ω for CSR2A

For HIGH section:

0.01Ω for CSR1A
0.49Ω for LSR2A
0.01Ω for CSR3A

LSR parameters for inductors have been calculated using:

http://www.pronine.ca/multind.htm

with assumed 1 inch coil inner diameter (d) and 1 inch coil length (l). For LOW section L1A inductor 16 AWG was assumed and for HIGH section L2A inductor 20 AWG was assumed.

CSR parameters were simply assumed ;)

More about parasitic parameters you can read at Parasitics subpage of Practice.
