© 2015 IEEE. Conventional model predictive power control (C-MPPC) requires a large amount of calculations, which is an obstacle for its application, especially in the multilevel converters. To solve this problem, this paper presents an efficient MPPC (E-MPPC) for three-level AC/DC converters by eliminating the complicated power predictions. As a result, the execute time and computational burden are reduced significantly while the control performance is not affected. Furthermore, the suppression of neutral point potential fluctuation and avoidance of high voltage jumps are also taken into account. A comparative study of the proposed E-MPPC and prior C-MPPC are presented in this paper. The effectiveness of the proposed method is validated by simulation and experimental results.
