Question

The circuit diagram of step-up type DC-DC converter is given below.

It is assumed that the output capacitor is large enough and the output voltage is constant.

(Consider that there is no circuit losses.)

Select an inductance value for the CCM operation state of the circuit. Assume that Output voltage (V_ç) is regulated and prove that the circuit will always have to work at CCM operation state for maximum input voltage and minimum output current.
