Abstract

The space vector pulse-width-modulation technique is extensively applied in the three-phase power electronics circuits because of its easy digital implementation and wide linear modulation range features. However, the attempt of this technique for the single-phase Z-source inverter has seldom been reported because of its unique topology and operational characteristics. In this paper, based on an in-depth mathematical derivation and theoretical explanation, the space vector pulse-width-modulation principles have been discussed in detail. Various implementation schemes are demonstrated, and a comparison study for selected switching patterns is conducted. In addition, the theoretical analysis is validated by both the simulation and experimental results. This work will be helpful for understanding the space vector pulse-width-modulation concept and modulation techniques of the single-phase full-bridge Z-source inverters.
