“…From the experimental results of the comparative case, by changing the value of the coordinator capacitor, the proposed topology can provide design freedom in any frequency band of interest. However, the interference suppression method they proposed is very difficult in practical applications and needs to be simplified [ 6 ].…”

With the rapid development of science and technology, testing equipment and testing methods are constantly updated. Radar detectors have the advantages of losslessness, high efficiency, high resolution, and high-speed radar image capture. They can accurately locate defects in railway tunnels, respond to hidden dangers in time, and provide strong technical support for transportation. This paper proposes to optimize the defect detection of railway tunnel radar through the combination of multisensor technology and active interference suppression algorithm and designs the corresponding sensor system according to the content. This article analyzes several factors that affect the radar detection effect and makes a detailed summary from the detection environment and other aspects. At the same time, it uses the multisensor system combined with active interference suppression algorithm to design a railway tunnel detection simulation experiment. Experimental results show that the use of multisensors combined with active interference suppression algorithm to optimize radar detection can effectively improve the accuracy of railway tunnel defect detection. Through the analysis of the results of tunnel defect detection, the detection accuracy of this paper has reached 98.8%, which can provide an effective reference for the detection of railway tunnels.

“…Figures 12c and 13c reveal that the LCL filter is able to not only reduce the THD but also reduce the DM EMI noise at the higher frequency range. Lower resonant frequency can lead to greater noise attenuation performance, as derived from Figure 8, and Equations (18) and (19). Figure 14 shows a comparison of the grid side current spectrum in the two types of LCL filters, one with copper wire inductor and the other with the copper foil inductor.…”

“…More accurate circuit components in the filter can be used in the simulation model to predict the noise at low and high frequencies. Figure 8 shows the common mode (CM) and differential mode (DM) EMI noise model with the LCL filter consideration; Equation (18) and Equation (19) are the CM and DM noise voltages, respectively. It can be found that the larger impedance of L i denotes the smaller noise voltage and reduced EMI filter requirement.…”

“…In a grid-connected inverter, the differential mode (DM) EMI is dominant compared with the common mode (CM) EMI; thus, the LCL filter can be treated as an EMI filter [18] in the high frequency range if the self-resonant frequency in the filtering inductor is high enough. The resonant frequency is relatively dependent on the parasitic components in the inductor [19]. Thus, if total harmonics distortion (THD) and EMI can be reduced at the same time with one filter, the power density would be increased pronouncedly.…”

The grid-injected current total harmonics distortion (THD) and electromagnetic interference (EMI) noise must be considered in a transformer-less grid-connected inverter for a more electric aircraft (MEA) system. This paper develops a procedure for the design of the magnetic components of the LCL filter used in harmonic control and EMI reduction of the silicon carbide (SiC) grid-connected inverter in the MEA. The LCL filter is designed with effective harmonic attenuation and a compact size. To meet the space constraint requirement, specific design attention is focused on a customized amorphous cored inductor, with a comprehensive study of the relationships of inductor winding with respect to EMI noise. Reduced THD and EMI are verified through experiments performed on a 30 kW, 230 V/400 Hz three-phase grid-connected inverter prototype with the LCL filter.
