摘　　要：本文首先阐述了传统Boost升压变换拓扑在较高直流母线电压下的应用与局限,然后综述了更适用于高输出电压、高功率等级下的多电平和多相Boost变换拓扑,并讨论了其在舰船应用中的优势与局限。最后,结合所综述的各类拓扑,本文还针对一种特定应用场合给出了相应的设计方案实例,阐释了其设计思路和综合考量。With the advancement of electrification and the growth of load demand,the power level of ship power system is continuously increasing.The two-stage power supply architecture with DC bus is an important type of power supply system,and its DC bus voltage has been increasing with the increase of power,from 400V in the past to more than 700 V.However,the ever-rising DC bus voltage presents new challenges to the front-stage Boost converters in responsible for DC bus voltage generation.To this end,this paper firstly illustrates the applications and limitations of the conventional Boost converter topology at higher DC bus voltages,and then discusses the advantages and restrictions of the multilevel and multiphase Boost converter topologies that are more applicable to high output voltages and high power levels in ship applications.Finally,in combination with the various topologies reviewed,a design example is presented for the specific ship application and the comprehensive considerations are described.
