摘要
为了提高中压直流系统DC-DC变流器的性能,本文对一种用于中压直流系统的DC-DC变流器拓扑及控制方法进行了分析和研究,提出采用基于低压DC-DC变流器的原边串联副边并联(ISOP)结构的拓扑,实现了电源的模块化和高功率密度,并简化了电源模块之间均压均流控制,仿真结果表明该系统可以实现预期运行范围的稳定工作。
In order to improve the performance of DC-DC converters in medium voltage DC power system,this paper studies a topology and control method of DC-DC converter for ship medium voltage DC power system.Based on low voltage DC-DC converter,ISOP structure is proposed,which achieves modular,high power density,and simplifies voltage/current balance control between modules.Simulation result shows the system can operate stably within expected running scope.
