GRID-CONNECTED PV SYSTEM EMPLOYING THREE INVERTERS REGULATED BY SYNCHRONOUS SCHEME OF PWM

The paper presents comparative analysis of three versions the modified scheme space-vector-based synchronous pulsewidth modulation (PWM), applied for control two-level inverters transformer-based photovoltaic (PV) system, and focused on providing symmetry winding voltage power transformer during whole adjustment range. Power supply is by corresponding solar strings consisting a set PV panels, outputs are connected specifically with inverter-side windings multi-winding grid-tired transformer. Results MATLAB-simulation prove fact advanced spectral composition triple-inverter-based installation regulated algorithms space-vector PWM, assuring potential reduction losses in these systems.
