摘要
传统的SRM(switched reluctance motor)功率变换器功率容量受到限制,只适用于中小功率的场合。为了扩大其应用范围,提出了五电平SRM功率变换器及其控制方法。该控制方法通过DSP物理实验表明,其五电平变换器器件开关次数可大大少于传统的功率变换器,不仅电流波形优于传统功率变换器,而且在同样耐压器件的情况下,五电平功率变换器的电压和容量将比传统三相不对称半桥结构提高1倍。
The traditional power capacity of SRM （switched reluctance motor） is being limited and only suitable for small and medium-sized power occasions. In order to expand the application scope, the five-level SR motor power converter and its control methods are proposed. The DSP physical experiment shows that the switch times of five-level converter is less than traditional SRM converter. The current wave is not only optimize than traditional power converter, but also the capacity of five-level converter is one time than traditional SRM converter under the same voltage compression.
