Abstract: This paper presented a novel single-phase space vector pulse width modulation （SPSVM） with shoot through zero vector. The principle of SPSVM,switch optimal mode and generating way of shoot through zero vector were analyzed. And then it was applied to the Z-source grid connected generation system with dual close loops of DC-link capacitor voltage and grid connected current. The robust predict current algorithm was introduced into the deadbeat controlling of grid connected current to increase the control precision and the dynamic performance,as well as depress the instability caused by the error between the value of practical inductance and the one in model. The simulation and experimental results of the system were given. The results verified the validity and feasibility.
