In this work, the authors have studied a quadratic boost DC-DC converter to reduce its ripple in the output voltage and the input current. This aim has been obtained by implementing two different solutions: the hardware solution consists on the use of coupled inductors and a notch output filter, the software solution is based on a random PWM and uses uncoupled inductors. The two solutions show a different impact on the output voltage and in the input current ripple. The performance of proposed solutions is evaluated and compared by simulation analysis both in time and frequency domain.

Abstract
In this work, the authors have studied a quadratic boost DC-DC converter to reduce its ripple in the output voltage and the input current. This aim has been obtained by implementing two different solutions: the hardware solution consists on the use of coupled inductors and a notch output filter, the software solution is based on a random PWM and uses uncoupled inductors. The two solutions show a different impact on the output voltage and in the input current ripple. The performance of proposed solutions is evaluated and compared by simulation analysis both in time and frequency domain.File in questo prodotto:
