A simplified SVPWM Control Strategy for PV Inverter
Space vector pulse width modulation (SVPWM) technology has widely application in inverter because of easy digital realization. However, in pulse wave generation, not only the trigonometric function is involved, but also sector selection will be considered when six vectors are calculated. The realization of SVPWM control algorithm is very complicated, although its control accuracy is high. Photovoltaic (PV) inverter is simplified DC/AC converter with respect to power driver system and it does not need complicated SVPWM. To solve the problem for PV inverter, a new simplified SVPWM control strategy is proposed. It has only comparison and normal arithmetical operations, so that the judgment of sector and calculation of vector operating time is completed. It eliminates the conventional SVPWM massive calculation of trigonometric function, and the system performance is improved. Simulation and experimental results show that the new SVPWM control strategy is feasible.
