摘要

本文研究了多级飞容逆变器在阶梯角控制下合成正弦波电压的最佳开关顺序。结果表明，选择适当的顺序可以使电容器电压和开关器件的电压和损耗达到平衡，并使负载电压THD值最小。提出了n电平逆变器的通用数学模型，该模型可方便地应用于任意工作模式的计算机仿真。

Analysis and control of a multi-level flying capacitor inverter

The paper presents the results of a study into the optimal switch mode sequence for a multi-level flying capacitor inverter to synthesis a sinewave voltage under staircase angle control. It is shown that a properly selected sequence will yield the voltage and loss balances in capacitor voltages and switching devices respectively and minimize the load voltage THD values. A general mathematical model for an N-level inverter is presented which can be conveniently applied for computer simulation of any operating mode.
