“…Refs. [17][18][19][20][21][22] consider several SHE PPWMs with identical eliminated harmonics while showing how the spectrum and total harmonic distortion of the converter voltage may differ at the same modulation factors. However, these studies are too limited, and the spectra are only provided for a few certain modulation factors, which do not allow for their full estimation.…”

The issue of converted voltage distortion by high-power converters at pulse-width modulation (PWM) with a low switching frequency of semiconductor modules is still relevant. Currently, the Programmed Pulse Pattern PWM (PPWM) technique is used extensively that allows pre-eliminating the selected harmonics from the converter’s voltage and current spectrum or reducing them to meet the voltage quality standard requirements. A review of scientific publications has shown the insufficiency of available studies on defining and estimating the impact of powerful converters with PPWM. The problem of defining the amplitudes of higher harmonics generated by a converter with PPWM, which are the main cause of electronic equipment failures at the common grid connection point, is particularly relevant. This study considers the behavior of the NPC converter voltage and current spectra at PPWM with the selected harmonic elimination (SHE) for three-level (3L) voltage waveforms. The behavior of up to the 50th non-eliminated harmonics in the NPC converter voltage and current spectra is first shown for a modulation factor changing within 0–1.15 at the pitch of 0.01 for six different SHE PPWM: no. 1–5 and 7; no. 2–5, 7, 11, and 13; no. 3–5, 7, 11, 13, 17, and 19; no. 4–5, 7, 11, 13, 17, 19, 23, and 25; no. 5–5, 7, 11, 13, 17, 19, 23, 25; 29, and 31; no. 6–5, 7, 11, 13, 17, 19, 23, 25, 29, 31, 35, and 37. The concept proposed herein allows measuring the current consumed amplitudes of NPC converter with SHE PPWM at the low average error of about 6%. The adequacy of the approach used herein to determine the current harmonic amplitudes has been experimentally verified with laboratory equipment. The results are consistent with engineering accuracy. The research work is promising for further study and estimation of the impact of the NPC converter SHE PPWM for more complex multi-pulse grid connection circuits and resonance phenomena.

“…Additionally, it shows how the switching function of the diode-rectifier influences the rectified current and generates the input currents that the ASD system uses (e.g., ia). It is found that the three-phase diode-rectifier is the primary contributor to current harmonics for the frequency range of 0-9 kHz [7]. Additionally, the operational power of other drive systems in the network has an impact on the amplitude of these current harmonics.…”

Modern industrial and commercial devices that are fed by power electronics circuits and behave non-linearly tend to produce power quality issues in power systems including harmonics and interharmonics, swell, flicker, spikes, notches, and transient instabilities. Among them, harmonic emission is the most significant challenge to be overcome by the distribution networks. Unwanted current, overheating motors and transformers, equipment failure, and circuit breaker misoperation are some of the harmonic consequences. While it is important to employ the best methods to mitigate or suppress the harmonic distortions in power systems, it is even more essential to estimate these harmonics at the outset by developing smart, efficient, and accurate techniques. Due to their capability for learning, predicting, and identifying, researchers have turned to Artificial Intelligence technologies for harmonic estimation in distribution networks. Although the power system parameters (impedance/admittance model) and many harmonic monitors are prerequisites for traditional harmonic estimation methods, by utilizing Artificial Intelligence, these requirements are minimized. In this paper, a comprehensive review of traditional and modern (smart) harmonic estimation techniques are discussed.

The power converters are essential for the development of renewable energy generation, conversion processes and energy storage systems. Besides, some applications require synchronization between converters e.g., industrial use as AC drives for motors, pumps, fans, drills and wheels. Thus, this paper presents a theoretical study with experimental validation of FPGA frequency and time synchronization conditions and its impact on conducted emissions (CE) from multidrives operations. For EMI assessment over those conditions, a LabVIEW-FPGAbased cyber-physical testbench was used to control the DC/AC converters using SPWM. It shows how the synchronization conditions impact the EMC in multiconverters systems over the EMI emissions and also highlights measures to mitigate the peak levels. The findings demonstrate that, depending on the condition, it reduces up to 29 dB of ground current peaks and 8 dB in EMI level, which may improve the EMC in DC distributed microgrids.
