Abstract In this paper, the functionality and performance of the current harmonic injection Dual-stage matrix converter (DSIMC) are investigated systematically. It is demonstrated that the dc-link capacitor could be removed through bidirectional implementation and proper control of the rectifier. Besides, the operating principles of DSIMC are analyzed in detail. Sophisticated algorithm for achieving sinusoidal input currents and significantly extending the input reactive power control range without lowering the voltage transfer ratio is developed, and mathematical description of the correctness of the algorithm is also provided. Based on the analysis of the operating principles, a detailed comparison between IMCs and DSIMC is presented. Moreover, modulation strategies of DSIMC are discussed, and the narrow pulse issue is analyzed and compared with that of IMCs. In addition, the system design is carried out, and the design criteria of the current harmonic injection inductor, considering both the current ripple and the harmonic current tracking performance, are introduced. Finally, the proposed method and all the theoretical analyses are verified by simulation and experimental studies. Top |
