How to extend the working duration is always a concern for IoT in the premise of increasing no battery capacity. Multi-frequency single-transmitter multiple-receiver wireless charging (MF-STMR-WC), designed to minimize the inductive cross-coupling effect, is well-suited for simultaneously charging multiple IoT devices. The key technique for MF-STMR-WC systems is the multi-frequency modulation method. Conventional methods primarily rely on pulsewidth modulation (PWM), offering independent power allocation but involving a high switching frequency. This article proposes a hybrid multi-frequency pulse modulation (HMFPM) method that combines pulsewidth and density modulation. By incorporating pulse density modulation (PDM), the switching frequency decreases, leading to reduced switching losses and improved efficiency. The experimental results verify the effectiveness of the proposed HMFPM method. In comparison to a conventional PWM method with the lowest switching frequency, the proposed method helps attain lower inverter power loss of up to 48.78% and higher power transfer efficiency of up to 7.32%.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"60 10","pages":"1-6"},"PeriodicalIF":2.1,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142204913","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article proposes a 3-D analytical model of the air-gap magnetic field for the AFPMC. The analytical model is based on the separation of variables method to solve the Laplace equation and Poisson equation in cylindrical coordinate system. The 3-D analytical magnetic field distribution is calculated by applying the magnetic scalar potential and the modified Bessel functions. According to the superposition principle, the air-gap flux density of driving and driven rotor PMs acting alone is synthesized to obtain the air-gap magnetic density of the AFPMC. Four regression evaluation metrics are used to assess the accuracy of the air-gap magnetic field. Finally, the magnetic field distribution, electromagnetic torque, and axial force calculated by the proposed 3-D analytical model are compared with the 3-D finite element analysis results.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"60 10","pages":"1-7"},"PeriodicalIF":2.1,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142204910","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article proposes a novel transmission line modeling (TLM) based parallel PEEC time-domain solver to solve nonlinear electromagnetic problems. The method substitutes both linear and nonlinear components in the standard PEEC equivalent circuit with corresponding TLM models, leading to an electrical current-based linear network and a magnetic current-based nonlinear network. The proposed TLM-PEEC method effectively decouples the nonlinear elements from the linear network, enabling individual solutions for the nonlinearities and making it highly suitable for parallel processing. Each nonlinear element is solved using parallel Newton-Raphson (N-R) iterations, and the analytical calculation of the Jacobian is presented along with the algorithm. The parallelization of the TLM-PEEC method is explored and implemented on a many-core graphics processing unit (GPU) and a multi-core central processing unit (CPU) to provide detailed field-oriented information on electromagnetic transients in a single-phase 2-D shell-type transformer. The proposed architecture was easily coupled with an external network, and the accuracy and computational efficiency of the TLM-PEEC method were verified through similar simulation results obtained from Comsol Multiphysics.","PeriodicalId":13405,"journal":{"name":"IEEE Transactions on Magnetics","volume":"60 10","pages":"1-9"},"PeriodicalIF":2.1,"publicationDate":"2024-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142204911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
