your time base is 5mS/div and you are looking at output voltage ( at what volts / div ?) ? into some sort of load ? - undefined by you,
a lot more information needed - including the power source you are running your converter from and the feedback loop you have come up with...
steel or iron is a poor choice for a lightning conductor as the self inductance is very high - meaning the lightning will seek other paths thru the building
lightning conductors are wide flat copper conductors for this very reason.
The standards show how to make a 50uH LISN inductor ( and the 250uH filtering one too ) there is no lower bound on the DC resistance - but the L must be damped according to the spec ( damping resistor every few turns ).
P & N = pos & neg.

A DC/DC converter with a soft start - and a with a load that is only gradually varied can handle 500uH on the input side if the control is suitably damped
else you will have to specify in the data sheet that 2200uF ( or what-ever ) external is to be...
500uH - on both P and N would be there to reduce noise from the mains upsetting the test.
50uH and large caps to earth on the mains side of these L's ( earth current hazard - be aware ) is the more usual approach - sometimes with 250uH upstream for the mains filtering reason...
much faster dynamics of the power stage as, controlling the peak ( or average ) current turns the buck inductor ( output inductor ) into a current source feeding a capacitor - rather than a double pole LC filter , there is still a Vout error amp stage to control the current level...
it's not though, here, if you read the text, the o/p of the EA is forced high, and an opto or similar is used to pull down the current limited o/p of the EA.
This is used a lot when the EA has to be on the other side of the isolation boundary
a quick read would have rendered your comment...
