The M_Transformer (or M Transformer) component models a multiwinding transformer with self and mutual inductances defined by a symmetric matrix.
Because the matrix_ is symmetric, it is specified by a one-dimensional array of length 12⁢N⁢N+1, Ljk : 1≤j≤k≤N, that represents the upper triangular portion of the matrix. For example, for a three-winding transformer, N=3 and the L array has the form L11,L12,L13,L22,L23,L33.
