摘要

In this paper, a new current regulator is applied for a 3-level NPC inverter to achieve both current regulation and neutral-point voltage balance. The performance of the proposed current regulator is validated for both sinusoidal current tracking, such as for a 3-level NPC inverter based motor drive application, and also for non-sinusoidal current tracking, such as for active filter application. Performance comparison and current regulator design considerations are addressed for sinusoidal and non-sinusoidal current tracking applications. Detailed simulation results are presented for performance validation of the new current regulator for both cases and the RMS current error is used as a performance index for comparison.
