摘要
从分解H桥级联型逆变器结构出发,研究了级联型逆变器与三相低压逆变器拓扑结构本质联系。级联型逆变器分解为多个H桥组后,每个H桥组继续分解后则为二电平逆变器简单的叠加。从而可以由二电平逆变器成熟、稳定的矢量调制技术推导出级联型逆变器矢量调制的实现。最后,仿真与实验结果验证了本文所提方法的正确性。
From the decomposition of H bridge cascaded inverter,the paper studies the essential topology relationship between cascade inverter and three-phase low voltage inverter.After breaking down a cascaded inverter into multiple groups H bridge,each H bridge group can been broken down into two-level inverter stack.So vector control of cascaded inverter can be derived from two-level inverters with mature and stable vector control technology.Finally,simulation and experimental results verify the correctness of the proposed method.
