Through coupling the impedance network between the grid and the conventional indirect matrix converter (IMC), the LC-filter-integrated quasi-Z-source (qZS) IMC overcomes the 0.866 voltage gain limitation of the conventional IMC and also avoids the input filter that is required to mitigate current harmonics of the conventional qZS matrix converters. This paper further investigates the voltage boosting...
The matrix converter solid state transformer (MC-SST), formed from the back-to-back connection of two three-to-single-phase matrix converters, is studied for use in the interconnection of two ac grids. The matrix converter topology provides a light weight and low volume single-stage bidirectional ac-ac power conversion without the need for a dc link. Thus, the lifetime limitations of dc-bus storage...
A novel three-phase/single-phase quasi-Z-source matrix converter (qZS-MC) is proposed in this paper. It extends the voltage gain of traditional MC and has the inherent benefits of MC. The circuit topology is analyzed, and the model is built, which discloses the relationship between the input current harmonic components, qZS impedance and output frequency. The suitable application area is suggested...
