To achieve the negative-sequence reactive power control, this article applies a single-phase transformer with low magnetizing inductance to the converter at the cost of exchangeable active and reactive power. The relationship of magnetizing inductance, active power, and reactive power is revealed in this article, and the operation of the converter under low magnetizing inductance is verified experimentally using a downscaled 110-V, 7.0-kVA model.","PeriodicalId":256507,"journal":{"name":"2022 International Power Electronics Conference (IPEC-Himeji 2022- ECCE Asia)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115584355","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 multi-cell topology effectively achieves high scalability by connecting cells in series and parallel. Generally, the multi-cell topology requires a lot of signal lines between the master control and slave controllers in order to control the power-sharing between the cell converters. Thus, the maintainability of the power converters is restricted with these wires. The proposed control scheme with a wireless communication for the EV charger requires no signal wires between master and slave controllers. The features of the proposed decentralized scheme are; 1)it allows communication delay of several hundred milliseconds, 2)each unit, which consists of three single-phase AC/DC converters, has an independent the slave controller.

Ball bearings are commonly used for motion restrictions; however, they cannot be applied to high-speed motors with large DN values. The rotor in this study has aerostatic bearing support in radial (x–y) and tilting (θx–θy) motions. However, if an additional magnetic bearing/actuator is applied to the motor for axial motion control (z), the motor size and shaft length increase. To avoid this problem, a novel bearingless motor structure with a magnetically integrated bearing function was developed in this study. The structure combines the functions of both torque production (θz) and axial force generation (z) in one unit. It uses only a set of three-phase slotless windings and three-phase voltage source inverter. Such bearingless motors are referred to as single-drive bearingless motors. The d-axis and q-axis currents regulate the axial suspension force and torque, respectively. This paper presents the structure, operation principle, 3D-finiete element calculation results, and experimental results. The fabricated prototype bearingless motor with a shaft diameter of 30 mm can actively control the axial motion of the rotor at 60,000 rpm, that is, with a DN value of 1,800,000.","PeriodicalId":256507,"journal":{"name":"2022 International Power Electronics Conference (IPEC-Himeji 2022- ECCE Asia)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116593220","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}
