Simulink model:-

Result/interleaved boost converter

* interleaved-boost converter, magnetically coupled to a voltage-doubler circuit, which provides a voltage gain far higher than that of the conventional boost topology.

* this converter has low-voltage stress across the switches, natural-voltage balancing between output capacitors, low-input current ripple, and magnetic components operating with the double of switching frequency.

* this converter suitable to applications where a large voltage step-up is demanded, such as grid-connected systems based on battery storage, renewable energies, and uninterruptible power system applications.

compare MATLAB results.

interleaved boost converter has low-input current ripple compare with boost converter so interleaved boost converter is much better.
