| 摘 要： | 含独立电源的级联H桥多电平变频器具有每个H桥单元结构相同、易于实现模块化设计等优点，因而在无功补偿和有源电力滤波器等领域有广泛的应用前景。在并联有源电力滤波器（APF）系统中，由于直流侧不需要提供有功功率，可充分利用级联多电平变频器的优势及载波相移PWM技术良好的谐波传输特性。提出了一种基于多电平变流器的并联APF系统的电路拓扑结构，并在交直流控制策略和系统参数设计方面进行了分析。仿真和实验结果表明，此系统动态响应速度快、补偿性能良好，验证了理论分析的正确性和实验系统的可行性。

| Abstract: | Cascaded H-bridge multilevel converter with separated DC source has the advantages of same strcture for each H-bridge and easy to realize modular design, which can be widely used in reactive power compensation and active power filter. In the system of shunt active power filter, owing to the DC side without supplying active power, the advantages of cascade multilevel converter and excellent harmonics transmission of carrier wave phase-shifting PWM technology are sufficiently utilized. It presents a shunt APF... |
