三相四电平三电容变换器中飞跨电容的实时寿命估计与监督电压调节

Three-phase four-level three-capacitor converter (3P4L3C) employs a single flying capacitor per phase, eliminating redundant switching states. However, this topology presents a significant challenge in capacitor voltage regulation, as conventional modulation techniques, including carrier-based SPWM and SVM, fail to maintain voltage balance. This article proposes a supervised voltage regulation met...
