The method is based on the probability learning iterative Fourier technique (PLIFT) with a fitness function to determine element distributions for large planar array thinning, which is denoted as FPLIFT here. Compared with the traditional methods, the PLIFT acquires a minimum sidelobe level and avoids the problem of local optimum. The fitness function is used to initialize the starting parameters of the position of the elements. Then, a probability density taper is adopted to model the element distributions across the aperture. The efficiency of the FPLIFT method was validated by a representative example of array thinning with minimum peak sidelobe level. It can be demonstrated by the simulated results that the FPLIFT inherits PLIFT advantages, and results in high efficiency in reducing the side lobes. Therefore, this proposed FPLIFT can be applied in synthesis and optimization of large-scale antenna arrays.","PeriodicalId":186847,"journal":{"name":"2022 Asia-Pacific International Symposium on Electromagnetic Compatibility (APEMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115288127","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The HF model contains only six circuit elements per phase with a simple structure and is intended for time-domain simulation of variable frequency drive (VFD) systems. The circuit elements are determined by a multilayer perceptron (MLP) neural network, in which only the phase-to-frame impedance is needed for training purposes. Compared with the parameterization methods in conventional motor modeling, the MLP significantly simplifies the parameterization process. Using a three-phase 5.5 kW star-connected induction motor as a case study, the capability and accuracy of the HF model are validated.","PeriodicalId":186847,"journal":{"name":"2022 Asia-Pacific International Symposium on Electromagnetic Compatibility (APEMC)","volume":"6 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120968266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this design, the lightning signal is converted into a digital signal through the analog-to-digital conversion chip AD9627. The sampling rate can reach 125MHz. A GPS module is applied to provide the UTC timestamp and the pulse per second (PPS) signal. The exact interval between sampling points can be obtained through the GPS PPS, and in combination with the UTC timestamp, the absolute time of each lightning data can be determined. This design allows the system to run automatically when the lightning signal reaches a set trigger voltage, and all triggered data will be stored in SD as a FATFS file. The data transfer and processing is implemented using the Verilog HDL in FPGA, and the following data storage is done in C language in the ARM processor. This design was completed in the official Xilinx software Vivado. The laboratory testing verified that the system design is stable and reliable.","PeriodicalId":186847,"journal":{"name":"2022 Asia-Pacific International Symposium on Electromagnetic Compatibility (APEMC)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125388632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
