Abstract

The development of fuel cell vehicles (FCVs) has a major impact on improving air quality and reducing other fossil-fuel-related problems. DC-DC boost converters with wide input voltage ranges and high gains are essential to fuel cells and DC buses in the powertrains of FCVs, helping to improve the low voltage of fuel cells and “soft” output characteristics. To build DC-DC converters with the desired performance, their topologies have been widely investigated and optimized. Aiming to obtain the optimal design of wide input range and high-gain DC-DC boost converter topologies for FCVs, a review of the research status of DC-DC boost converters based on an impedance network is presented. Additionally, an evaluation system for DC-DC topologies for FCVs is constructed, providing a reference for designing wide input range and high-gain boost converters. The evaluation system uses eight indexes to comprehensively evaluate the performance of DC-DC boost converters for FCVs. On this basis, issues about DC-DC converters for FCVs are discussed, and future research directions are proposed. The main future research directions of DC-DC converter for FCVs include utilizing a DC-DC converter to realize online monitoring of the water content in FCs and designing buck-boost DC-DC converters suitable for high-power commercial FCVs.

基于宽输入电压范围高增益阻抗网络的燃料电池汽车DC-DC变换器拓扑研究进展

燃料电池汽车（FCV）的发展对改善空气质量和减少其他化石燃料相关问题产生了重大影响。具有宽输入电压范围和高增益的DC-DC升压转换器对于FCV动力系统中的燃料电池和DC总线至关重要，有助于改善燃料电池的低电压和“软”输出特性。为了构建具有所需性能的DC-DC转换器，对其拓扑结构进行了广泛的研究和优化。为了获得FCV宽输入范围、高增益DC-DC升压变换器拓扑的优化设计，综述了基于阻抗网络的DC-DC升压转换器的研究现状。此外，还构建了FCV DC-DC拓扑结构的评估系统，为设计宽输入范围、高增益升压转换器提供了参考。该评价系统采用8个指标对FCV用DC-DC升压变换器的性能进行了综合评价。在此基础上，对FCV直流-直流变换器的相关问题进行了讨论，并提出了未来的研究方向。用于FCV的DC-DC转换器未来的主要研究方向包括利用DC-DC转换器实现对FCs中含水量的在线监测，以及设计适用于大功率商用FCV的降压-升压DC-DC转换器。
