Abstract

Compared to using uncontrolled rectifier, the use of active rectifier can significantly improve the output power of doubly salient electric generator (DSEG). The traditional six-state-angle-control (SSAC) strategy has limited effectiveness in improving the output power of DSEG. A mathematical model of DSEG in a rotating coordinate system oriented by back electromotive force (EMF) vector was established based on the principle of instantaneous reactive power. The reason why SSAC strategy is difficult to further improve the output power of DSEG was analyzed through this model. To address this issue, this paper proposed a back EMF oriented vector control (BEFOVC) strategy. Compared with SSAC strategy, BEFOVC can further optimize the output performance of DSEG, reduce copper loss, phase current peak and THD, and suppress the torque ripple of DSEG. Finally, the feasibility and effectiveness of the proposed method were verified through simulations and experiments on a 12/8-pole DSEG.

期刊介绍： IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest. IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on: Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals. Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering. Development of new or improved fabrication or manufacturing techniques. Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
