Abstract


This paper develops successfully SVPWM voltage vector tracking current control model for three-phase grid-connected inverter and a novel current scheme under two phase synchronous rotating frame is presented, which is using grid feed forward controller. Considering the efficiency of photovoltaic modules, using an improved maximum power tracking algorithm. The simulation results show that the inverter has high output power factor and photovoltaic system has good dynamic performance and tracking result.
