Abstract
This paper proposes a simplified SVPWM for three level inverters in transformerless photovoltaic (PV) systems. With the proposed SVPWM the three level space vector (SV) diagram is divided into only six sectors as in conventional two level SV diagram in such a way that only seven SVs are used among all the available SVs of three level inverter. The main features of the proposed SVPWM are that it is simple to implement, less switching losses as compared to conventional SVPWM and most importantly it eliminates the leakage currents in transformerless PV systems. Detailed theoretical analysis of the proposed SVPWM are presented and verified by numerical simulations and experimental results.
