    Do you know how to interpret the results of the .four command in ltspice……

    The attached LTspice offline flyback smps , when using the .four command for 50Hz , gives a spice error log which says harmonic number 1 is 50Hz and then says “Fourier component” is 0.2195.

    What does the 0.2195 mean?

    The RMS input current is 157mA
