To address the inefficiency and high cost of the traditional energy-consuming hydrogen generation power supply test platform,a novel back-to-back pair-tow experimental scheme for hydrogen generation rectifier power supplies is proposed.The scheme operates with load through two sets of hydrogen production power supplies back-to-back,and develops detailed power-side and load-side control strategies,aiming to improve the dynamic response performance and solve the problem of mismatch between power levels,operating voltages and current ranges of the load-side power supplies.The validity and feasibility of the proposed experimental scheme are confirmed by pair-tow experiments on single and four-unit parallel-connected whole machine,which provide new ideas and technical support for the optimized design and performance evaluation of the hydrogen production rectifier power supply.This study is of great significance for improving the overall performance and reducing the operating cost of the hydrogen production system.
