一种基于开关电容的十三电平逆变器.

In view of the problems of large volume, high cost and complex structure of the existing multilevel inverter topology, a 13 level inverter based on switched capacitor is proposed. The proposed topology is composed of a DC input power supply, 3 capacitors and 14 switching devices, which realizes a 13 level output with 6 times boost. The proposed topology has lower cost and smaller volume, reduces the harmonic content of the system output, and realizes the inverter without H - bridge to reduce the voltage stress of the switch tube. The proposed inverter can achieve capacitor voltage self - balancing without any auxiliary method, which simplifies the complexity of control. The superiority of the proposed topology is verified by comparison with other traditional multilevel inverters. Simulation and experimental results verification on the simulation and prototype platform prove that the inverter has good performance in both steady and dynamic conditions. [ABSTRACT FROM AUTHOR]
