A wavelet modulation method for a quasi-Z-source inverter

工程科学学报, 2017
A wavelet modulation strategy applied to a quasi-Z-source inverter was proposed. The regulating range of the shootthrough duty ratio could be increased by changing the locations of the sampling points set using traditional wavelet-modulation.

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.
