This paper proposes a high‐power hydrogen converter specifically designed for megawatt‐level (MW‐scale) off‐grid hydrogen production systems powered by renewable energy sources. A two‐stage ISOP architecture is adopted to fulfill the demanding requirements of high voltage step‐up, high efficiency, low output ripple, and reliable power regulation.

In this paper, a modified isolated Z‐source AC–AC converter with inherent commutation and reduced polarity changer switches is proposed. This converter enables flexible output voltage adjustment, determined by two degrees of freedom—namely, the high‐frequency transformer turns ratio and the duty cycle.
