PWM: amplitude [0; V_in], period T, duty cycle $α$ .

Continuous conduction when: $I_{o u t 1} \geq \frac{(1 - α) . α . T . V_{i n}}{2 L_{1}}$

Discontinuous conduction when: $I_{o u t 1} < \frac{(1 - α) . α . T . V_{i n}}{2 L_{1}}$

Continuous conduction: $V_{o u t 1} = α . V_{i n}$

$V_{o u t 2} = \frac{n_{2}}{n_{1}} V_{o u t 1}$

Discontinuous conduction: $V_{o u t 1} = \frac{V_{i n}}{1 + \frac{2 L_{1} . I_{o u t}}{α^{2} . T . V_{i n}}}$

$V_{o u t 2} = \frac{n_{2}}{n_{1}} V_{o u t 1}$
