摘要

本文介绍了三电平中性点箝位(NPC)逆变器电容电压平衡的软件方法与硬件方法的比较。我们的方法修改了空间向量。我们增加了一个新的变量来调整中间电压矢量的驻留分布次数，如下所示为连接电压的行为。通过仿真比较了两种方法的有效性。

Software method versus hardware method to balance capacitors voltages for three level NPC converter

This paper presents a comparison between our software method for balancing capacitors voltages for three-level neutral-point-clamped (NPC) inverters and hardware method. Our method modifies the space vector. We append a new variable to adjust the dwelling distribution times of middle voltages vectors as follows the connection voltages behavior. We give simulations to compare the validity of the two methods.
