摘要

光伏发电电解水制氢能够进一步提高光伏发电利用率，针对光伏制氢系统需工作在较宽范围输出电压的特点，提出一种基于多谐振变换器的直流耦合光伏制氢系统，能够满足氢能的高效制取。分析多谐振变换器的工作原理，引入序列二次规划法对多谐振变换器进行参数设计，解决多谐振变换器参数设计较为复杂的问题。在此基础上设计试验样机，并在试验样机对设计参数进行验证，验证结果表明：基于多谐振变换器的光伏制氢系统硬件电路参数设计合理，能满足变换器宽增益（输出电压200～650 V）、高效率（97.24%）的需求，降低了变换器因无功功率循环而造成的损耗，提高了光伏制氢效率。

Abstract

Photovoltaic water electrolysis hydrogen production can improve the utilization rate of photovoltaic solar hydrogen production system further

while it needs to work in a wide range of output voltage. A DC-coupled photovoltaic hydrogen production system based on multi-resonant converter is proposed

which can meet the efficient production of hydrogen energy. The working principle of the multi-resonant converter is analyzed

and the sequence quadratic planning method is introduced to solve the complicated parameter design of the multi-resonance converter. On this basis

the experimental prototype is designed and verified. The experimental results show that

the hardware circuit parameters of the photovoltaic hydrogen production system based on the multi-resonant converter has reasonable design

which can meet the requirements of width gain(output voltage 200～650 V) and high efficiency(97.24%) of the converter

reduce the loss caused by the converter due to reactive power cycle

and enhance the efficiency of photovoltaic hydrogen production.
