“…The compensation brings the harmonics down to 1.89 % which is as per the recommendations of IEEE 519 -2014 standards. In comparison with the statistics of THD reported in literature review, this value is much less than that of Mengi 4.17% [26], kota 3.46% [29] and of Shuvo 3.17% [28]. Table 2 shows comparison of proposed system with those of literature for current THD values.…”

Multilevel converters have received serious attention on account of their capability of high voltage operation, high efficiency, and low electromagnetic interference. It has many advantages compared to conventional two-level inverters such as high dc-link voltages, reduced harmonic distortion, fewer voltage stresses, and low electromagnetic interferences. The multilevel converters have been used for STATCOM widely as it can improve the power rating of the compensator to make it suitable for medium or high-voltage high power applications. While deploying multilevel STATCOMs, designer's role is to reduce the number of switching devices since, the total switching losses are proportional to the number of switching devices. The reduction in the count of switching devices also reduces the size and cost. In this paper, a five-level modified cascaded H-bridge inverter STATCOM is proposed for mitigation of harmonics. Modified Five-level CHB configuration is the most suitable as with lesser number of switches, give better performance resulting in a compact system. The PQ theory-based controller is developed for control of STATCOM operation. MATLAB simulation results are presented to demonstrate mitigation of harmonics.

This paper deals with the detailed review and comparative analysis of latest reduced switch multilevel inverter topologies for electric vehicle applications. The recent trends in reduced‐switch multilevel inverters are discussed. Detailed review of the reduced‐switch multilevel inverter topologies, their merits and demerits, and the comparative analysis based on component count, total harmonic distortion, and efficiency are conducted. This paper gives a detailed review of recent trends in reduced‐switch multilevel inverter topologies for electric vehicle applications. Switching pattern of the topologies is provided for better understanding of the inverter operation. Comparative analysis of the reduced‐switch inverter topologies based on the component count, total harmonic distortion of output voltage, and efficiency is also presented in this paper. Based on the comparative analysis, it is observed that the interleaved nine‐level flying capacitor multilevel inverter topology achieved the lowest output voltage distortion of 1.6%, which is within the acceptable limits of IEEE 519‐2014 standard. It is observed that the three‐level active neutral point clamped multilevel inverter topology achieved the highest working efficiency of 99.4%. This paper discusses the most recent trends in reduced‐switch multilevel inverters. A comprehensive review of the recent publications and a crisp comparative analysis of the different inverter configurations based on component count, harmonic distortion of output voltage, and efficiency are presented in this paper.
