Abstract
With an increase in the abnormalities in the supply voltage, it is required that the Adjustable Speed Drive (ASD) connected to the grid be immune to those disturbances. Based on the field Power Quality (PQ) data study, distortion in the supply voltage is found to be the dominant disturbance followed by unbalance. It is found that these disturbances mainly affect the lifetime of dc bus capacitor and in critical cases, it may lead to a failure. In order to save the ASD from such grid disturbances, a compensation module is introduced in this article. While reducing the stress on the capacitor, this module also mitigates the harmonics in the source current of ASD. The proposed module can be a retrofit to the existing commercial ASD and can be used where the supply voltage quality is poor. The proposed topology is analyzed by simulations and validated by the test setup created in the lab.
期刊介绍：
The IEEE Transactions on Power Electronics journal covers all issues of widespread or generic interest to engineers who work in the field of power electronics. The Journal editors will enforce standards and a review policy equivalent to the IEEE Transactions, and only papers of high technical quality will be accepted. Papers which treat new and novel device, circuit or system issues which are of generic interest to power electronics engineers are published. Papers which are not within the scope of this Journal will be forwarded to the appropriate IEEE Journal or Transactions editors. Examples of papers which would be more appropriately published in other Journals or Transactions include: 1) Papers describing semiconductor or electron device physics. These papers would be more appropriate for the IEEE Transactions on Electron Devices. 2) Papers describing applications in specific areas: e.g., industry, instrumentation, utility power systems, aerospace, industrial electronics, etc. These papers would be more appropriate for the Transactions of the Society which is concerned with these applications. 3) Papers describing magnetic materials and magnetic device physics. These papers would be more appropriate for the IEEE Transactions on Magnetics. 4) Papers on machine theory. These papers would be more appropriate for the IEEE Transactions on Power Systems. While original papers of significant technical content will comprise the major portion of the Journal, tutorial papers and papers of historical value are also reviewed for publication.
