摘要

多电平电流源逆变器以其高安全性和低输出di/dt而受到广泛关注。为了用更少的器件产生更多的电平,降低电路成本,简化控制方法,提出了一种带开关电感的多电平非对称电流源逆变器拓扑结构。本文介绍了逆变器的拓扑结构、工作原理、调制策略和电感电流控制方法。最后,通过计算机仿真验证了理论分析的正确性。

A Multilevel Asymmetric Current Source Inverter Topology Using Switched Inductor
Multilevel current source inverter has attracted extensive attention because of its high security and low output di/dt. In order to generate more levels with fewer devices, reduce the circuit cost and simplify control method, a new multilevel asymmetric current source inverter topology with switched inductor is proposed. In this paper, the inverter topology, working principle, modulation strategy and inductor current control method are described. Finally, the correctness of the theoretical analysis is verified by computer simulation.
