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.
