“…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].

“…The 5-level modified CHB STATCOM of Yamnaz [25] is configured for providing the reactive power compensationa and the harmonics part is left unaddressed. Mengi [26] has repored 4.94% voltage THD and 4.17% current THD with 5-level STATCOM. Some benefits of the five-level Cascaded H-Bridge topology include: The working cycles and power losses are uniformly dispersed, and the modularity is quite high [27].…”

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.

Sürekli Mıknatıslı Doğru Akım (PMDC) Motorları hız kontrol uygulamalarında ve konum kontrolünün önemli olduğu durumlarda kullanılan gelişmiş elektrik motorlarıdır. Dolayısıyla bu motorların benzetimi ve kontrolü üzerine pek çok uygulama bulunmaktadır. Güneş enerji sistemleri günümüzde yaygın olarak kullanılan ve gelecekte kullanımı artacak olan bir yenilenebilir enerji kaynağıdır. Bu çalışmada güneş enerji sistemleri için PMDC motorun ayrıntılı matematiksel denklemlerinden yola çıkılarak benzetimi yapılmakta ve iki serbestlik dereceli PI (2-DOF PI) kontrolör devresi kullanılarak sistemin kontrolü gerçekleştirilmektedir. Benzetim çalışmaları MATLAB/Simulink ortamında gerçekleştirilmiştir.

SummaryIt is generally impossible to control the inverter output current (IOC) based on operator needs if only pulse width modulation (PWM) techniques are used. Conventionally, authors have reported the finite control set‐based predictive current control algorithm (FCS‐PCCA) to control the IOC with a fast dynamic response. However, this type of algorithm without a PWM stage generates a variable switching frequency (VSF) of operation, and it leads to filter design problems, inequitable thermal stress, and more current distortions that have been presented. To alleviate all these issues, a new generalized PCCA with the integration of a fractional part function‐based single carrier modulation technique (G‐PCCA‐FPF‐SCMT) has been proposed, and it provides constant switching frequency (CSF) of operation. In this technique, the normalized optimum inverter output voltage (N‐O‐IOV) has been fed with FPF‐SCMT. The particular modulation stage implementation is straightforward since even inverter level number increases, the number of references and triangular carrier signals is always only one. The complete control implementation process of the proposed technique is extremely low compared with all traditional CSF‐based PCCAs. To verify the proposed technique experimentally in both steady and transient state operations, one of the conventional five‐level switched capacitor‐based inverter topologies has been considered and elucidated vividly in both open‐loop and closed‐loop operations.
