摘要
船舰应急电源(Uninterruptible Power Supply,UPS)广泛应用于海上平台、轮船等环境中的关键设备供电,可在主电源故障时保障重要负载持续稳定运行。逆变器作为UPS系统的核心部件,其性能直接影响供电质量。然而,传统逆变器仅具备降压功能,难以直接满足不同电气设备对交流电压等级的多样化需求。针对这一问题,对一种具备升压能力的新型逆变器拓扑及其在船舰UPS系统中的应用进行了研究。首先分析了该逆变器的拓扑结构和工作原理,并对其控制策略进行了详细介绍。在此基础上,搭建了仿真模型并进行测试。结果验证了所提拓扑在升压性能和供电稳定性方面的有效性,表明该升压型逆变器在船舶应急电源中具有良好的应用可行性。
Uninterruptible Power Supply(UPS)systems are extensively deployed in critical equipment at maritime platforms and vessels,ensuring continuous operation of essential loads during primary power failures.As the core component of UPS systems,inverters directly determine power quality.However,conventional inverters with limited voltage reduction capabilities struggle to meet diverse AC voltage requirements across electrical devices.To address this,this study investigated a novel boost-capable inverter topology and its implementation in marine UPS systems.The research first analyzed the inverter's structural design and operational principles,followed by detailed control strategy implementation.Through simulation modeling and field testing,the proposed topology demonstrates superior voltage enhancement performance and power supply stability,confirming its practical viability for emergency power solutions in marine environments.
