Voltage integration in LTspice (net volts across inductor)

Flyback

Well-Known Member
Hi,
I am trying to see if the following “sdt” function in LTspice will integrate the voltage across the secondary of the current sense transformer? AYK, It should integrate out to zero volts, but its rising away negative.
Have i done the integration right?
LTspice and PNG attached.
