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。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.
