Transformer

Transformer with two ports  Description The Transformer component models a two-winding transformer as a two-port with each port having self and mutual inductances. Equations ${i}_{1}={i}_{\mathrm{p1}}=-{i}_{\mathrm{n1}}$ ${i}_{2}={i}_{\mathrm{p2}}=-{i}_{\mathrm{n2}}$ ${v}_{1}={v}_{\mathrm{p1}}-{v}_{\mathrm{n1}}={L}_{1}\stackrel{.}{{i}_{1}}+M\stackrel{.}{{i}_{2}}$ ${v}_{2}={v}_{\mathrm{p2}}-{v}_{\mathrm{n2}}=M\stackrel{.}{{i}_{2}}+{L}_{2}\stackrel{.}{{i}_{2}}$ Variables
