Open AccessInterleaved step-down converter with capacitor-diode voltage splitter and minimum switches for low current ripple and extra-low voltage ratio
This paper proposes an interleaved step-down converter (ISDC) with a capacitor-diode voltage splitter. Even though the ISDC only utilizes two active switches, it can significantly step down a high input voltag...
