Abstract

To address the stringent power requirements of high-efficiency electrolysis-based hydrogen production systems

which demand low current ripple

high output current

and low output voltage

this paper presents a high step-down ratio interleaved DC/DC converter utilizing coupled inductors. The proposed converter incorporates a flyback capacitor structure

effectively limiting the maximum voltage stress on the power devices to half of the input voltage

thereby improving system safety and reliability. Through the implementation of time-division multiplexing with coupled inductors

the converter achieves soft-switching operation

which significantly reduces switching losses at high frequencies. Additionally

the interleaved design mitigates output current ripple

thereby enhancing dynamic performance and system stability. Simulation and experimental results corroborate that the proposed converter exhibits superior soft-switching characteristics

minimal current ripple

reduced output voltage

and satisfies the stringent power quality standards required for high-efficiency hydrogen production systems.
