摘要
变频电源的核心部件是变频器,系统采用了级联型高压变频器。介绍了岸电变频电源的工作原理以及优点。介绍了变频器逆变侧的闭环载波移相SPWM控制。仿真模型大体由三个模块组成,包括移相变压器模块、变频器模块和控制模块。通过对变频电源仿真分析,可以看出电源的质量良好。
The core of frequency conversion power is the inverter,the system uses the cascaded high voltage inverter.The principles and advantages of shore power supply are introduced.The closed- loop carriers phase- shifted SPWM control of inverter is introduced.The simulation model consists of three modules,including the phase- shifting transformermodule,invertermoduleand controlmodule.Wecanseethatthepowersupplyqualityisverygood fromthesimulationanalysisoftheinverterpowersupply.
