“…Total Harmonic Distortion (THD) is a measure of the effective value of the harmonic components of a distorted waveform and it is commonly used for a quick measure of distortion [581]. THD implementations in FPGA have the highest PDLY in this category (43% of documents in the last three years) and these have been implemented in FPGAs for multilevel inverters [582][583][584][585], AC (Alternating Current) LED (Light-Emitting Diode) drivers [586][587][588][589]. Interpolation with FPGAs have been used for video scaling [590][591][592] and motion estimator for High Efficient Video Coding (HEVC) encoder [593][594][595].…”

Field Programmable Gate Array (FPGA) is a general purpose programmable logic device that can be configured by a customer after manufacturing to perform from a simple logic gate operations to complex systems on chip or even artificial intelligence systems. Scientific publications related to FPGA started in 1992 and, up to now, we found more than 70,000 documents in the two leading scientific databases (Scopus and Clarivative Web of Science). These publications show the vast range of applications based on FPGAs, from the new mechanism that enables the magnetic suspension system for the kilogram redefinition, to the Mars rovers’ navigation systems. This paper reviews the top FPGAs’ applications by a scientometric analysis in ScientoPy, covering publications related to FPGAs from 1992 to 2018. Here we found the top 150 applications that we divided into the following categories: digital control, communication interfaces, networking, computer security, cryptography techniques, machine learning, digital signal processing, image and video processing, big data, computer algorithms and other applications. Also, we present an evolution and trend analysis of the related applications.

Reduction of total harmonic distortion in multilevel inverters is a difficult optimization problem that includes nonlinear transcendent equations having more than one local minima.This paper deals with the harmonic elimination of cascaded multilevel inverter with equal D.C. sources using a new optimization technique. The objective of this paper is to find the best combination of switching angles to minimize the lower order harmonics and the total harmonic distortion is reduced. For this purpose, a new optimization techniques i.e. whale optimization technique is considered.This algorithm is applied to an 11-level cascaded H-bridge inverter.Results shows that WOA gives better results and effectively minimizes the THD and lower order harmonics

“…Symmetric Cascaded H-Bridge converter has been investigated with different types of modulation techniques, such as Space Vector Modulation (SVM) [12], Selective Harmonic Elimination (SHE) [7], [13], Selective Harmonic Mitigation (SHM) [14], and Sinusoidal Pulse Width Modulation (SPWM) [15], [16]. Among all, SPWM technique is simpler to be implementated [17].…”

<span lang="EN-US">The conventional three-level inverter has been proposed to act as a recuperating converter in Traction Supply Substation. This converter is mainly used to feed back the regenerative braking energy to the grid. However, passive filter is desired to mitigate the current and voltage harmonics. Therefore, this paper investigates the possibility to use a seven-level Cascaded H-Bridge (CHB) converter as the recuperating converter without additional filtering. The proposed converter is modeled with MATLAB/Simulink simulation software. It is then simulated with two potential modulation schemes, namely Phase-Shifted PWM (PS-PWM) and Phase-Disposition PWM (PD-PWM). The quality of AC waveforms produced by these two modulation methods is compared and studied. The results show that PS-PWM technique is preferable for this application as it offered a clean AC current waveform with less than 5% harmonic distortion. However, a twenty-one-level CHB was predicted to comply with the 8% voltage harmonic requirement.</span>
