How does the leakage inductor distribute over multiple coupled inductors?
I am working in LTspice with a triple coupled magnetic inductor. I chose the factor of coupling to be 90%. L_1 is 1000uH so the uncoupled energy should be 100uH. How does the 100uH energy distribute ...

How can I determine how much power is in a frequency range via FFT in LTspice?
When using LTspice, I can see the FFT of a voltage. How can I see how much power is in a particular frequency band, and what portion of the total power it is?
The FFT in LTspice is in dB, but it's ...
