摘要
为了实现中压直流4 kV至低压直流710 V的变换,设计了一种应用于舰船中压直流电网中的三电平直流变换器,分析了该变换器的工作原理,设计了滤波元件参数和控制器,并进行了仿真验证。最后,根据设计方案制造了一台实验样机。实验结果表明:设计方案合理可行,该变换器动态性能良好,功率密度和效率均高。
A three-level(TL)dc-dc converter is proposed for vessel medium voltage direct current(MVDC)application,in order to realize conversion between medium voltage dc 4kV and low voltage dc 710V.The operation,filter,and controller of this converter is analyzed and designed,which is ve-rified by simulation.Finally,a prototype is built and tested.Experiments validate the design and si-mulation,and show that the dynamic response is fast,and the power density and efficiency are high.
