Step 3 Formulate the network equations using the equivalents

Considering the interconnections between subcircuits in the FIBC converter shown in Fig. 6.3 the following relationship can be obtained.

Based on KVL, we can get the relationship between different port voltages in Eq. (6.64).

$\{\begin{array}{l}{v}_{i1}^1=v_{i1}^2=v_{i1}^3=v_{i1}^4=v_{i1}^5=v_{i1}^6\\ v_{i2}^6=v_{i2}^2=v_{i2}^3\\ v_{i3}^6=v_{i3}^4=v_{i3}^5\end{array}.$ (6.64)

$v_{i1}^1,v_{i2}^6,v_{i3}^6$ can be selected as the independent input voltages of the six subcircuits. ...
