Abstract

This paper proposes a dual-Trans-quasi Z-source three-level indirect matrix converter (DTrans-qZs TLIMC). A dual-Trans-qZs network is located in the DC-link of a TLIMC to provide a stable virtual neutral point for the inverter stage and to increase the voltage gain of the converter. The space vector pulse width modulation (SVPWM) strategy is proposed to control the DTrans-qZs TLIMC. By analyzing the small signal model of the DTrans-qZs network, the analysis result of the impact of the rectifier stage output voltage pulsation on the operating characteristics of the DTrans-qZs network can be obtained, and the modulation ratio of the inverter stage can be corrected in real time. By analyzing the voltage transfer ratio of the DTrans-qZs TLIMC, the calculation expression of the maximum voltage transfer ratio can be obtained. Finally, experiments are performed to verify the correctness of the topology and its modulation strategy.
