Abstract Z-source inverter photovoltaic system is a single-stage system, which has buck/boost characteristic. It achieves maximum power point tracking (MPPT) with control shoot-through duty cycle, while fulfills the grid-connection with modulation index control. This paper presents a single-stage control technique for Z-source inverter based PV system. The new unified vector is composed of the traditional vector U and the boost factor , which allows the desired vector to be located anywhere without limitation of the dc input voltage. The output voltage of Z-source inverter can faithfully follow the reference voltage regardless of the variable dc-link input voltage. It increases modulation index M, full utilizes the dc-link input voltage, decreases voltage stress of the active devices and improves the harmonics in output current of the inverter. The theoretical analysis is verified by simulation and experimental results.
