Physical signal input port associated with the control signal. The output voltages are [v_a v_b v_c] = S. For an ideal sinusoidal source, input three sine waves that have the requisite amplitude and phase delays of $$\left[\begin{array}{ccc}0& -\frac{2\pi }{3}& \frac{2\pi }{3}\end{array}\right]$$.

Electrical conserving port associated with the neutral phase.

Expandable three-phase port associated with the output voltage.

Electrical conserving port associated with the a-phase output voltage.

Electrical conserving port associated with the b-phase output voltage.

Electrical conserving port associated with the c-phase output voltage.
