This paper presents a simplified space vector pulse width modulation (SVPWM) method for three-level T-type quasi-Z-source (qZS) photovoltaic (PV) inverters. The proposed SVPWM method achieves multi-functionalities for the qZS T-type PV inverter, such as boosting the PV voltage, controlling the neutral point (NP) voltage, and reducing the common mode voltage (CMV), while preserving simplified implementation. The shoot-through duty cycle is added uniformly during the switching cycles, whereas, the redundant small voltage vectors are employed for controlling the NP voltage. The complex computations and cascaded proportional-integral (PI) control algorithms of the conventional SVPWM methods are eliminated in the proposed SVPWM. Thence, the proposed SVPWM can dramatically reduce the computation burdens. The performance of the new proposed SVPWM algorithm has been demonstrated using comprehensive simulation studies for various operating points, dynamics and imbalance conditions. Keywords photovoltaic
