today i was playing around wit PSUD2 to simulate how would my new hand wound air core inductors would fair in a CLC filter against CRC.
the air core inductors are made with 13 AWG wire, around 1.5 inch of diameter and 1 inch length - around 80 turns. each of these weigh 500 grams have a resistance of 0.1 ohms. on calculating the inductance turns out to be measly somewhere around 350uH [micro Henries].
simulation on PSUD2 is far from encouraging. i was under the impression that if not indcutance, atleast resistance [0.1 ohm] in the coil would act as CRC.
CLC simulation:
CRC [R at 0.25 ohms]:
interestingly if i run the simulation for CRC with 0.1 ohms resistance, the output graph is very close to above CRC.
this is the first time i'm using PSUD2 and not sure if i've set parameters correctly. to look at it has simple UI.
so low value inductor is bad in filtering even with inherent coil resistance?
