An Edge-Aligned Modulation Technique to Suppress Leakage Current in the Back-to-Back Neutral-Point Clamped Converter

This article investigates the effect of the leakage current on the back-to-back neutral-point clamped (BTBNPC) converter. The analysis indicates the leakage current of the BTBNPC converter is closely associated with the difference of the common-mode voltage (CMV) between the rectifier and the invert...
