Hi there,
Hopefully this can be simply answered.
Can somebody please tell me how inductance is measured when in a DC application?
I found a datasheet on an DC choke where they measure inductance based upon a DC current through the inductor.
Im aware of the formulas below but not sure how they arrive at this inductance value...
Xl = j2∏fL
and..
Vl(t) = di/dt L
So if they rate an inductance at 3H with test conditions of a Max voltage of 600VDC and 500mA how do they get that given di/dt is 0.
What would be the equivalent at 240V 500mA 50Hz?
Thanks in advance!
