TSFA 25 1019 / Cheesy Fan #3 : Achieving Very Low SRF (Self Resonant Frequency).
As we start to look at the properties of this contraption… here is part 3… In this video we start looking at how we have lowered the SFR (Self Resonant Frequency) of the coil quite a lot just by changing the interconnections. However we also changed the Q of the coil dramatically. we are introducing a lot of impedance by adding greater difference in potential between the winding’s.
