一种提高寿命并减小飞跨电容尺寸的单相七电平嵌套开关电容变换器

This article introduces a seven-level nested switched-capacitor (7L-NSC) inverter topology designed to reduce the flying capacitors and extend their operational lifetime. The proposed 7L-NSC topology utilizes two symmetrical flying capacitors, each rated at one-third of the dc source voltage. The redundant switching states along with a capacitor voltage balancing method based on an overall priorit...
