摘要： In this paper, analysis of circulating currents of paralleled single-phase boost converter systems is presented. The dc loop and ac loop circulating currents are clearly explained. In order to eliminate the dc loop circulating currents and reduce switching losses, a simplified pulsewidth modulation strategy is adopted in a paralleled single-phase boost converter. Based on the analysis of circulating currents, common-mode circulating current (CMCC) and differential-mode circulating current (DMCC) are defined. Then, CMCC and DMCC compensators are proposed in a centralized control scheme to reduce the common-mode and differential-mode circulating currents in a parallel system operated in both rectifier and inverter modes with different power sharing for microgrid applications. Converter-paralleled system stability analysis is also presented. Finally, a prototype system is constructed to facilitate the theoretical results as verification. From the experimental results, the proposed control scheme can indeed reduce the circulating currents under equal and/or different power rating conditions in the parallel system. 其他題名： TIA 出版者： New York: IEEE 出版日期： 2014-03-01 出處： IEEE transactions on industry applications, 2014-03, Vol.50 (2), p.1304-1312 資源來源： IEEE Xplore 版權： Copyright The Institute of Electrical and Electronics Engineers, Inc.
