In Reply to: Choke inductance - lower currents? posted by vbenonisen on March 2, 2012 at 14:22:43:
hey,
Unless specifically designed to do so (swinging choke), inductors remain reasonably linear with DC current from 0 to the rated DC current.
By reducing the DC current and increasing the AC current you typically get more inductance due to cores having higher permeability at higher flux levels but with this higher flux the chances of mechanical noise also increases.
It is also important to understand that mechanical noises are a function of build parameters and tell you that you are operating at an AC (or AC+DC) level that the build cannot keep stable.
