Abstract
For the special requirements of grid-connected inverter used in wind power generation system
a kind of three-phase Z-Source inverter operational principle is analyzed in this paper.Formulas for the design of main parameters under the control of constant duty cycle of shoot-through switching state are derived.Then the simulation models of SVPWM with shoot-through zero vectors are built by Matlab/Simulink in order to control the switch of Z-Source inverter on and off.The independent control strategy of d-axis...
