해상풍력용 3-level 3상 NPC Inverter 데드타임 보상방법

This paper described deadtime compensation method of 3-level 3 phase NPC Inverter using offshore power. Current distortion occurred from dead time. Therefore, in order to compensate current distortion, switch turn on period is differently applied according to output current direction and reference voltage. In this paper, theoretic analysis was verified through simulation.
