Bus Capacitance fluctuation Equalization Control system for cascaded multilevel Inverters based on cyclic path

摘要:

传统控制级联多电平逆变器的频率偏差较大，性能不稳定。为此，设计一种级联多电平逆变器母线电容波动均衡控制系统。在调频盲卷积开发平台的基础上，协调母线电容大数据采集器及均衡控制器的连接方式，完成新型系统的硬件运行环境搭建。利用线性聚类控制程序中的目标节点，移植调频盲卷积的协议栈及规划大数据的循环路径，完成新型系统的软件运行环境搭建，实现基于循环路径的级联多电平逆变器母线电容波动均衡控制系统的搭建。对比试验结果表明，与传统系统相比，应用均衡控制系统后，时域、频域调频波仿真波形的控制有效性均能达到65%以上。

Abstract:

The conventional control cascade multilevel inverter has large frequency deviation and unstable performance. Therefore, a cascaded multilevel inverter bus capacitor fluctuation equalization control system is designed. On the basis of the blind convolution development platform of frequency modulation, the connection mode of bus capacitor big data collector and equalizer controller is coordinated, and the hardware operating environment of the new system is built. By using the target node in the linear clustering control program, the protocol stack of blind convolution of FM is transplanted and the cycle path of big data is planned to complete the software running environment of the new system. The bus capacitance fluctuation equalization control system of cascaded multilevel inverter based on cyclic path is implemented. The experimental results show that, compared with the traditional system, the control effectiveness of the simulation waveforms in time domain and frequency domain can reach more than 65% after applying the equalization control system.
