摘要

本文提出了一种新型的三电平二极管箝位整流器中性点稳压器，该稳压器采用快速空间矢量调制器和共享函数控制器进行中性点调节。冗余状态选择通过连续共享函数进行控制，并以该共享函数作为控制变量，开发了闭环调节器的小信号模型。当使用稳压器时，在中性点的电压失真中可以看到显着的改善，这导致所需直流母线电容的明确降低。

Modeling and design of a neutral point regulator for a three level diode clamped rectifier

This paper proposes a novel neutral point voltage regulator for a three level diode clamped rectifier, which uses a fast space vector modulator in conjunction with a sharing function controller for neutral point regulation. Redundant state choices are controlled via a continuous sharing function, and small signal models are developed for closed loop regulators with this sharing function as the control variable. A significant improvement is seen in the voltage distortion at the neutral point when the regulator is used and this leads to a definitive reduction in the required DC bus capacitance.
