中文摘要 | 为了解决无环流循环变频器输出频率受限的问题,本文提出了基于变压器移相级联的高压交交变频拓扑。本文采用了一种新型的基于测量每一个桥臂的管压降的零电流检测方法。为了防止了误发“假有电流”信号,设计了相应的检测电路。仿真和实验表明,该拓扑能够提高输出电压和频率,减小谐波污染,适用于高压大容量的舰船电力推进系统。; To solve the problem of limited output-frequency in cycloconverter, a high voltage AC-AC converter topology based on phase shift transformer is presented. The paper adopts a novel strategy of zero-crossing detection based on measuring voltage drop of each bridge’s leg. A relevant measuring circuit is designed to prevent false current from emitting. Simulations and experiments results show the improvement of output voltage with higher frequency and low harmonics by the proposed topology is very suitable for high voltage marine electric propulsion system. |
