摘要

本文介绍了一种具有有源电压平衡控制的调制器，用于直接由6kv交流电网供电的基于电动机驱动的三相四电平FLC变换器。介绍了在闭环中采用P控制器实现飞行电容电压平衡的移相PWM调制驱动的调制算法。在额定功率为35kva的小尺寸驱动样机上进行了实验，验证了该控制方法的有效性。

Modulator for 4-level flying capacitor converter with active voltage balancing control with P controllers

This paper presents modulator with active voltage balancing control for three-phase four-level FLC converter based electric motor drive for applications supplied directly from a 6 kV ac-grid. It describes modulation algorithm of the drive with phase shifted PWM modulation with balancing voltage of flying capacitor by using P controllers in the closed loop. The proposed control is verified by experiments carried out on down-scale drive prototype of rated power of 35 kVA.
