Abstract
- Two new configurations of static ground power unit based on 5L active neutral point clamped (ANPC) and novel modular 9L-ANPC converter are proposed. First, a new level shifted phase-shifted carrier pulse-width modulation (LS-PSC-PWM) switching method for the 5L-ANPC converter is defined. By utilizing the proposed method, total harmonic distortion of output voltage is reduced in comparison with traditional PSC-PWM switching method. Then, a novel modular 9L-ANPC multilevel converter and its suggested modulation method is proposed in this paper. In comparison with traditional 9L-ANPC converter, the main advantages of proposed modular 9L-ANPC converter are halving the applied voltages on flying capacitors (FC), reduced number of FCs, and self-balancing of FCs, which is provided by suggested switching method. This results in reduction of the size and cost of converter, and makes it more feasible and reliable. Furthermore, inductance reduction of output LC filter enhances static ground power unit dynamic performances. The simulation and experimental results verified the feasibility and performance of proposed converters. [ABSTRACT FROM PUBLISHER]
