Abstract

Current source inverter (CSI) operates to output a specified ac current waveform from dc current sources. Talking about power quality, harmonics distortion of ac waveform is a problem of an inverter circuit. Generating a multilevel current waveform will have less harmonics content than a traditional three-level current waveform. In addition to non-ideal conditions of power switches, i.e. voltage drop in diodes, conductors or controlled switches, the performance of current controller applied in an inverter circuit will considerably affect the ac waveform quality produced by inverter circuit. This paper presents and discusses application of hysteresis current controller in the five-level H-bridge with inductor-cell current source inverter. The current controller performance was compared with the proportional integral current controller. Some test results are presented and discussed to explore the advantages of hysteresis controller in reducing the current ripple and harmonics distortion of output current.

利用磁滞电流控制器改善电感电池型五电平CSI的输出电流

电流源逆变器(CSI)从直流电流源输出指定的交流电流波形。谈到电能质量，交流波形的谐波失真是逆变电路的一个问题。与传统的三电平电流波形相比，产生多电平电流波形具有更少的谐波含量。除了功率开关的非理想状态，即二极管、导体或受控开关的压降外，逆变电路中应用的电流控制器的性能也会对逆变电路产生的交流波形质量产生很大影响。本文介绍并讨论了磁滞电流控制器在电感-单元电流源型五电平h桥逆变器中的应用。比较了该电流控制器与比例积分电流控制器的性能。给出了一些测试结果并进行了讨论，以探讨迟滞控制器在减少电流纹波和输出电流谐波畸变方面的优势。
