Three Phase Trans-Quasi-Z-Source Inverter
CPSS Transactions on Power Electronics and Applications, 2018 In this paper, a new type of single-stage boost Transquasi- Z-source inverter topology is presented. The basic structure and working principle of the inverter are analyzed and its voltage gain is deduced. The model of the Trans-quasi-Z-source network is established by using Laplace transform.
