摘要
船舶应急电源对于保障船舶的安全可靠行驶起着重要的作用,可以在船舶供电系统故障时,及时为应急负载提供短时电力供应。本文对双向全桥DC-DC变换器的拓扑结构、工作原理和控制策略进行分析和研究,并尝试将变换器应用于船舶应急电源的应用场合。在此基础上,本文搭建了原理样机,并对主要的参数和波形进行测试,取得了预期的效果,验证了双向全桥DC-DC变换器在船舶应急电源中应用的可行性。
The ship emergency power supply system plays an important role to ensure the security of the ship,can be in the ship power system failure,can provide short- term power supply for the emergency load timely. In this paper,the bidirectional full bridge DC- DC converter are studied,the converter topology structure,working principle and control strategy are analyzed and the researched,and applied the converter to the ship emergency power supply applications. Above all,this paper set up a principle prototype,and tested the main parameters and waveforms,and achieved the expected results,the function of the bi-directional DC- DC full bridge converter the feasibility of application in ship emergency power are verified.
