Abstract: This article introduces a quadratic boost converter topology that has a low input current ripple compared to other quadratic boost traditional topologies. The proposed converter is inspired by the LCL filter; one of the inductors in the traditional converter is split into two inductors and a capacitor. The proposed converter has more components than its previous version, but two of its inductors are equivalent to the second inductor in the traditional quadratic boost, providing a non-increase in the size while reducing the switching ripple at the input current. These findings suggest that the proposed design is a viable alternative for applications where a quadratic gain is required while a small input current ripple is desirable. A comparative evaluation with a design showed the proposed converter reduced 20% in the stored energy of inductors and still has a reduction of more than 40% in the input current ripple. Simulation and experimental results are provided to demonstrate the principle of the proposition.
