“…The forward voltage drop, however, is reduced by half at the voltage doubler because only one diode reduces the input voltage during the forward conduction. These results are consistent with the fact that the bridge rectifier is not suitable for low power applications [17].…”

“…As shown in Figure 3A, the conducted EMI signal is composed of multiple sinusoidal signals that have a different amplitude, respectively, depending on its frequency. From the superposition theory in [17], the source voltage resulting from summation of n sinusoidal signals can be approximated with an envelope that is expressed

A novel energy harvesting technique that uses conducted electromagnetic interference as an energy source is presented. Conducted EMI generated from fluorescent light using a switched‐mode power supply was measured and modeled as an equivalent voltage source. Two types of rectifier circuits—a bridge rectifier and a voltage doubler—were used as the harvesting devices for conducted EMI source. The matching networks were designed based on the equivalent model, and the harvested power was improved. The implemented energy harvester produces a regulated power over 68.9 mW and current over 15.1 mA while a regulated voltage can be selected between 3.3 V and 5 V. The proposed system shows the highest harvesting power indoor environment and can provide enough power for the Internet of Things devices.

“…These devices generate a set of high-level narrowband emissions at the switching frequencies and their harmonics in the range from 9 to 150 kHz [2]- [5]. Engines or lighting devices also generate high-level noise in frequencies up to 150 kHz [5], [6]. The increasing number of such devices leads to more frequent and higher (nonintentional) disturbances in the grid in frequencies currently used for data transmission by PLC (intentional emissions).…”

This study proposes a novel measurement method to assess the disturbances in the electrical grid for the CISPR Band A (9 to 150 kHz), as no normative grid measurement method for these frequencies exists yet. Compatibility levels in IEC 61000-2-2 in this frequency range are defined based on the CISPR 16-1-1 method using the quasi-peak (QP) detector. However, this method is not directly applicable for grid measurements as it was originally designed for laboratory conditions and for measuring radio disturbances and immunity. The method proposed in this paper (Light-QP method) overcomes these limitations, along with lower complexity, computational burden and memory requirements than CISPR 16-1-1. The Light-QP method uses a digital quasi-peak detector that processes Root Mean Square (RMS) values of spectral components, calculated by adapting the IEC 61000-4-7 standard to the CISPR Band A. The proposed Light-QP method is applied to real measurements from a Low Voltage (LV) distribution grid and compared to the quasi-peak outputs from a digital implementation of the CISPR 16-1-1 method. The results are comparable and can be used for assessment against compatibility levels. The Light-QP method has been presented to IEC SC77A/WG9 for its potential inclusion as a normative measurement method in a new version of the IEC 61000-4-30 standard.

NB-PLC (narrowband power line communication) is a method of data communication that involves superimposing a relatively high-frequency signal (9 kHz to 500 kHz), which contains data, onto the power grid’s low frequency (50 to 60 Hz) signal. While using the existing power grid as a transmission medium is convenient, the power grid was not designed for this purpose, leading to challenges such as conduction emission and infrastructure limitations. To overcome these technical challenges, passive filters are necessary. This article presents the design, simulation (using scattering parameters), and evaluation of an NB-PLC filter by comparing it to commercially available filters. Our proposed design and benchmarking methods enable the accurate prediction of the filter’s behavior in field conditions. After comparing our filter with commercially available filters, we observed that it exhibits superior characteristics. Specifically, our filter has the best insertion loss versus frequency, achieved three times higher attenuation at 50 kHz (−130 dB) compared to the best commercially available filter (−40 dB), and has a power consumption of 0.6 W, which is comparable to the most power-efficient commercial filter (0.5 W). Additionally, our filter has the second best input and output impedance of 3.6 Ω within the frequency range of 35–95 kHz.
