Multilevel converters

直到最近，绝大多数电力电子应用都是在低压系统中。然而，在过去十年中，高压半导体开关的发展在高压电力电子应用中产生了显著的活动。 传统的两电平变换器在高压应用中存在显著的问题-高输出dv/dt损坏绝缘和电机轴承，并且半导体开关具有高开关损耗。 多电平转换器有望缓解这些问题。该项目将研究和开发用于静态无功补偿器和中压驱动器的多电平换流器技术，最初针对采矿应用。

Until recently the vast majority of power electronic applications have been to low voltage systems. However, developments in high voltage semiconductor switches in the last decade have generated significant activity in high voltage power electronic applications. Traditional two level converters have significant problems in high voltage applications - high output dv/dt damages insulation and motor bearings, and the semiconductor switches have high switching losses. Multilevel converters hold the promise of alleviating these problems. This project will research and develop multilevel converter technology for static VAR compensators and medium voltage drives, initially targeted at mining applications.
