摘要

针对现有氢燃料电池用并网变流器系统直流侧存在的升压能力不足、纹波抑制能力较弱、开关过电流风险较高等技术难题,提出三相并联准Z源直流升压两级式氢燃料电池用并网变流器（TPPQZSTSDBHFC-GCC）系统。首先,建立质子交换膜氢燃料电池输出电压、电流及功率的数学模型,揭示其功率-电压-电流的输出关系及响应特性;其次,基于燃料电池输出特性,提出TPPQZSTSDBHFC-GCC拓扑结构,详细分析其工作原理及纹波抑制能力等特征,结果表明所提拓扑结构在实现高电压增益的同时也具备低纹波、低过电流风险、稳态性能好等优良特性;通过仿真与实现验证了所提拓扑的正确性与有效性。

Abstract

In response to the technical challenges associated with the DC side of existing grid-connected converter systems for hydrogen fuel cells, namely insufficient boost capability, poor ripple suppression and a high risk of switching overcurrent, a three-phase, parallel quasi-Z-source, two-stage DC-boost grid-connected converter system for hydrogen fuel cells （TPPQZSTSDBHFC-GCC） is proposed. Firstly, a mathematical model of the output voltage, current and power of a proton exchange membrane hydrogen fuel cell is established, revealing its power-voltage-current output relationship and response characteristics; Secondly, based on the fuel cell’s output characteristics, the TPPQZSTSDBHFC-GCC topology is proposed, and its operating principles and features, such as ripple suppression capability, are analysed in detail. The results indicate that the proposed topology structure achieves high voltage gain while also exhibiting excellent characteristics such as low ripple, low risk of overcurrent, and good steady-state performance. The correctness and effectiveness of the proposed topology are verified through simulation and implementation.
