| 摘 要： | 分析了一种基于多电平控制的高压变频器拓扑结构,通过采用带中间抽头的输出变压器,完成三电平逆变模块的串、并联连接,从而实现变频器高压、大电流的多电平输出。同时,采用优化输出电压波形的控制方法,有效抑制了输出电压的特定谐波,因此该结构的变频器适用于对变频器输出谐波敏感的大功率负载。

| Abstract: | The research and implementation of a multilevel high power converter is presented in this paper.This kind of converter consists of two inverter modules and each inverter module is based on three-level topology.In the primary winding of the output transformer there is an additional center-tapped terminal,so the two inverter modules can be connected in series or parallel as desired.It can provide big current in parallel mode and provide high voltage in series mode.In order to eliminate the selected harmonic of the output waveform,an optimized control method is applied and the result is perfect.So this kind of con-verter is suitable for the heavy loads which are sensitive to the harmonics of the converter. |
