Title
Decomposition-Based New Space Vector Modulation Algorithm for Three-Level Inverter with Various ADSVPWM Strategies.
Abstract
The three-level inverter is extensively preferred in medium-voltage industrial applications over the conventional inverter due to its benefits. The performance of inverter is better when the space vector modulation (SVM) approach is preferred. However, the implementation of conventional SVM approach is more complex. In this paper, a decomposition-based new SVM algorithm for three-level inverter is proposed to reduce computational complexity and implementation time using a low-cost digital controller. Initially, the performance of the proposed SVM algorithm is studied through MATLAB simulation using the conventional switching sequence 0127. Further enhancing the performance, the proposed algorithm is implemented with various advanced discontinuous SVPWM strategies using the advanced switching sequences of 1012-2721 and 0121-7212. The no-load motor current THD and switching loss analysis for ADSVPWM and conventional SVPWM strategies at different modulation indices are presented is this paper for a comparison point of view. The no load motor current THD results obtained through simulation are validated experimentally by implementing the proposed algorithm on real-time interface tool through dSPACE, which is used to control constant V/F-controlled three-level inverter-fed induction motor. Further to show the effectiveness of the proposed technique, the experimental investigation is done on induction motor at loaded condition and the results are presented.
