Abstract

In this paper, advanced DC-Link (DCL) based reversing voltage type Multilevel Inverter (MLI) topologies by compensating the difficulties in the conventional MLIs are reviewed. These topologies consist of less switching components and driver circuits when compared with conventional MLIs predominantly in higher levels. Consequently, installation area, total cost and hardware difficulties are reduced by increasing the voltage levels. The unipolar based Pulse Width Modulation Schemes (PWMS) will improve DCL inverters performance. This paper presents unipolar Multi-Reference (MR) based sine and space vector PWMS with single triangular carrier wave for generating required levels in output voltage. Comparison between UMR sine and space vector PWMS for DCL inverter topologies is presented in terms of Fundamental Output Voltage (FOV) and Total Harmonic Distortion (THD). The research tries to establish the survey analysis for single-phase 7-level DCL based reversing voltage type MLI topologies with UMR based sine and space vector PWMs. Finally, to confirm the feasibility of proposed DCL-MLIs in terms of FOV and THD the simulation results are incorporated. Further, the prototype model is developed for single-phase 7-level DCL inverter with Field Programmable Gate Array (FPGA) based UMR sine and space vector PWMS to authenticate simulation results. The efficiency of the proposed cascaded MLI achieves the value of 99.003%.

先进的基于直流环节的反向电压型多电平逆变器拓扑结构的评估

本文综述了通过补偿传统MLI中的困难而提出的先进的基于直流链路（DCL）的反向电压型多电平逆变器（MLI）拓扑。与主要在更高级别中的传统MLI相比，这些拓扑结构由更少的开关元件和驱动电路组成。因此，通过增加电压电平，减少了安装面积、总成本和硬件困难。基于单极的脉宽调制方案（PWMS）将提高DCL逆变器的性能。本文提出了一种基于单极多参考（MR）的正弦和空间矢量PWMS，具有单个三角形载波，用于产生所需的输出电压电平。从基本输出电压（FOV）和总谐波失真（THD）的角度对DCL逆变器拓扑结构的UMR正弦和空间矢量PWMS进行了比较。本研究试图建立基于UMR的正弦和空间矢量PWM的单相7电平DCL反向电压型MLI拓扑的调查分析。最后，为了验证所提出的DCL MLI在FOV和THD方面的可行性，结合了仿真结果。此外，利用基于现场可编程门阵列（FPGA）的UMR正弦和空间矢量PWMS，开发了单相7电平DCL逆变器的原型模型，以验证仿真结果。所提出的级联MLI的效率达到了99.003%。
