A new three-phase “one-step” boost type matrix converter

Due to the structural design of the traditional matrix converter, the voltage transfer ratio is limited to 0.866. In this paper, we purposed a new one-step boost type matrix converter, which can change the voltage transfer ratio variable from the perspective of changing the topological structure. The topological structure of one-step boost type matrix converter not only improved the voltage transfer ratio, but also achieved the voltage transfer ratio regulating circuit and waveform modulation frequency conversion circuit that was made one. In a switching cycle, realized the function of improving voltage and waveform modulation at the same time. It coordinated the chopper modulation with the high-frequency boosting that achieved one-step of the boosting and the frequency conversion. Meanwhile, it also helps to make the voltage transmission easier and enhance the reliability of commutation so as to solve the problem of low ratio.
