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

在包括铁路、可再生能源、国防和配电在内的广泛应用中，对高功率和中压能量转换系统的需求不断增长。多单元型多电平转换器是满足这种需求的非常有吸引力的手段，但前提是单元电压可以被精确地调节，以便确保转换器的保护，同时确保具有所需频谱质量的切换波形的合成。该项目提供了消除使用多单元转换器技术的障碍的可能性。此外，该项目强调开发和培训熟练设计和开发这项技术的人员。

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.
