Therefore based on Fig. 8, and (36) the minimum value of inductor\(L_{1}\) (\(L_{1min}\)) is as follows:
\(L_{1min}=\frac{V_{\text{in}}(1-D)}{F_{s}\Delta_{{i}_{L1}}}\) (37)
In (37), \(V_{\text{in}}\)and \(F_{s}\) are the input voltage and switching frequency. Also the minimum value of inductor \(L_{3}\) is calculated based on (30).
