摘要
目前的多电平变换技术主要是针对电压型逆变器。随着超导储能技术的发展,电流型逆变器的储能效率问题必将得到解决,电流型多电平逆变器也将得到广泛应用。详细介绍了一种新型电流型三相直接式五电平拓扑,研究了该拓扑的控制策略。给出了仿真和实验波形,仿真结果和实验波形验证了文中所做的分析。
The multilevel converter technology has been mainly used for voltage source inverters （VSI＇s） by now. But with the development of the superconducting magnetic energy storage （SMES） technology, superconducting inductors can be used as higher efficiency energy storage elements, the application of multilevel current source inverters （CSI＇s） in power systems will be more and more popular. A new kind of three-phase direct type five-level CSI topology is presented. The control strategy of the topology is studied. The proposition is verified by the simulation results and the experimental waveforms.
