具有增强电压增益的可扩展双向开关电容多电平逆变器

In this article, a novel switched-capacitor basic cell is introduced as the building block of a multilevel power-electronic inverter. Two distinct modulation strategies are proposed that control how the capacitors are charged. The two modulation strategies enable different utilization of capacitor voltages, number of voltage levels, and dc-to-ac voltage gains. The operations of the two-cell and th...
