Boost

PWM: amplitude [0; V_in], période T, rapport cyclique $\alpha$.

Conduction continue si: $I_{out}\ge \frac{(1-\alpha ).\alpha .T.V_{in}}{2L}$

Conduction discontinue si: $I_{out}<\frac{(1-\alpha ).\alpha .T.V_{in}}{2L}$

Conduction continue: $V_{out}=\alpha .V_{in}$

Conduction discontinue: $V_{out}=V_{in}+\frac{{\alpha }^2.T.{V_{in}}^2}{2L.I_{out}}$
