“…The high-frequency switching of third-generation semiconductor devices is the main factor required to generate switching EMI, and so the high-frequency modeling of the switching device must accurately simulate its transient characteristics [30]. The method used to model a switching device creates a circuit behavior model and a physical model.…”

With the development of high-frequency, miniaturized, and lightweight power electronic devices, third-generation semiconductor devices are more and more used in the main circuits of power electronic converters. The electromagnetic interference (EMI) generated by their fast switching can affect the performance of power electronic converters. Therefore, it is necessary to investigate the modeling and suppression methods of conducted noise in power electronic converters of third-generation semiconductor devices. This paper describes the EMI sources and coupling paths of EMI in third-generation semiconductor devices used in power electronic converters. The modeling methods of EMI are summarized from the perspectives of power devices and coupling paths. The suppression methods of conducted noise are summarized by suppressing EMI sources and improving coupling path characteristics. This paper provides a reference for the electromagnetic compatibility design of power electronic converters for third-generation semiconductor devices.

“…Therefore, appropriately configured and reliable FAS must be used to ensure the technical security of CI facilities. When operating FAS in CI facilities with a very high reliability and availability index, we provide an adequate fire safety level [7,[112][113][114]. It is particularly important in public utility CI facilities.…”

The article reviews issues associated with the use of electronic fire alarm systems (FAS). They are operated in various environments and buildings with varying volumes. FAS have to function properly under different operating conditions associated with their operation, as well as power supply and information inflow. Due to their functions, i.e., ensuring the safety of people, vehicles, logistics bases, airports, etc., FAS have to exhibit an appropriately organized reliability structure associated with their implementation and power supply. Operational studies involving FAS operated in various facilities were conducted to this end. The authors determined damage and recovery time intensities. FAS reliability indicators were also determined. The article presents graphs associated with developing the energy balance for selected FAS. The graphs are consistent with the latest and applicable legal regulations. The next stage of the work related to this article was developing an FAS operation process model and conducting computer simulations in order to determine reliability indicators. Such an approach to the FAS operation process enables a rational selection of technical and organizational solutions aimed at guaranteeing reliability in the course of executing operational tasks associated with ensuring fire safety. FAS operational analysis, developing balance graphs and models, as well as the computer simulation, enabled inferring conclusions that might be useful to the process of engineering and operating such systems.

“…On this basis, each design of a multiobjective optimization would collect ≥ 1.2 G samples of the input current to ensure compliance with conducted emissions standards. Alternatively, double Fourier integral analysis [6] on the grid current i g is possible too, but this approach is always solved numerically and requires a high computation cost when the number of voltage levels increases [7], [8].…”

Multi-level (ML) converters are frequently used to implement grid-tied ac-dc conversion systems. Their design may benefit from multi-objective optimization techniques, which typically involves time-consuming circuit simulations in order to obtain input current estimations suitable for input inductor and EMI filters design. Herein, a closed-form expression of the input current ripple is derived to ease harmonic content estimations. The proposed approach separates the fundamental grid-current component from its ripple and models the latter like an amplitude modulation, where the modulating signal is its envelope and the carrier is the triangular current waveform. First, a general waveform analysis of ML converters is performed to derive the voltage across the grid-side inductor, then the associated current ripple is modeled. Experimental results on an ML converter prototype are reported to validate the analytical results.
