Improved Capacitor Voltage Balance for Multicell Power Electronic Converters Controlled by Spectrally Optimal Modulation

在铁路、可再生能源、国防和配电等广泛应用中，对高功率和中压能量转换系统的需求日益增长。多单元类型的多电平转换器是满足这一需求的一种非常有吸引力的手段，但前提是单元电压可以被精确调节，以确保对转换器的保护，同时确保合成具有所需频谱质量的开关波形。该项目为使用多单元转换器技术消除这一障碍提供了可能性。此外，该项目还强调发展和培训这项技术的设计和开发方面的技术人员。

There is a growing demand for high power and medium voltage energy conversion systems in a wide range of applications, including Rail, Renewable Energy, Defence and Electricity Distribution. Multicell-type multilevel converters are a very attractive means of satisfying this demand, but only if the cell voltages can be precisely regulated so as to ensure protection of the converter while simultaneously ensuring the synthesis of switched waveforms with the required spectral quality. This project offers the potential to eliminate this barrier to the use of Multicell converter technology. In addition this project emphasises the development and training of people skilled in the design and development of this technology.
