Abstract

In high power industrial drive use the multi modular converter for high voltage dc transmission system. The reduction of switching frequency, reduce thermal stress and harmonic distortion in the output of the converter by using the modular converter. Synchronous optimal pulse width modulation (SOP) is a developing low gadget exchanging recurrence regulation system for high power converters, which keeps up the nature of converter output current. SOP system has been effectively exhibited for established multilevel topologies and it has been demonstrated that greatest gadget exchanging recurrence can be restricted to evaluated principal recurrence for seven or larger amount inverters without trading off on the nature of yield streams. Be that as it may, execution of SOP procedure for MMC topology is as yet pending. One of the primary difficulties for control of MMC is to keep up drifting capacitor voltages around their ostensible esteem. The objective of our investigation is to propose, break down and actualize improved SOP strategy for MMCs to accomplish low device exchanging recurrence operation, better quality of converter output current and keep up capacitor voltages around their perceived value.

基于高级控制拓扑的模块化变换器的性能与实现
在大功率工业驱动中,多模块变换器用于高压直流传动系统。采用模块化变换器可以降低开关频率,减少变换器输出的热应力和谐波畸变。同步最优脉宽调制(SOP)是一种用于大功率变换器的、保持变换器输出电流特性的、正在发展中的低器件交换循环调节系统。SOP系统已经有效地展示了已建立的多层拓扑结构,并且已经证明,对于七个或更大数量的逆变器,最大的小工具交换递归可以被限制为评估主递归,而不会对收益流的性质进行交易。尽管如此,MMC拓扑的SOP程序仍有待执行。控制MMC的主要困难之一是保持电容器电压在表面上的波动。我们的研究目的是提出、分解和实施改进的SOP策略,以实现mmc的低器件交换重复操作,更好地实现变换器输出电流的质量,并保持电容器电压在其感知值附近。
