摘要：This paper presents a three phase transformerless photovoltaic inverter for grid tied PV system. A three phase grid is connected to the photovoltaic system with maximum power point tracking (MPPT), along with fuzzy logic controller is used, the control strategy is applied based on p-q theory for better utilization of the photovoltaic system, according to this strategy during sunlight the system sends active power to the grid and at the same time compensates the reactive power of the load. In case there is no sunlight (during the night for instance), the inverter only compensates the reactive power of the load. The advantage of this strategy is the operation of the photovoltaic system the whole day.
