摘要
氢能是一种清洁能源,其使用可以缓解当今世界资源短缺的现状。本文将氢燃料电池作为电动车的主要动力来源,为解决其混合动力系统中燃料利用效率不高、燃料电池寿命不长、燃料汽车续航里程不够等问题,选用两相交错并联buck电路作为变换器,设计功率分配单元,搭建了氢燃料电池车混合动力系统仿真模型,仿真结果验证了该系统能够为负载提供充足的动力,且动态响应迅速。
Hydrogen energy is a kind of clean energy which can alleviate the shortage of resources in the world. In this paper, hydrogen fuel cells are used as the main power source for electric vehicles. In order to solve the problems of low fuel efficiency, short fuel cell life, and insufficient fuel mileage in hybrid systems, a two-phase interleaved parallel buck circuit is used as the converter, designed the power distribution unit, built the hydrogen fuel cell vehicle hybrid power system simulation model. The simulation results verify that the system can provide sufficient power for the load and has fast dynamic response.
