Abstract

A transformerless 3-phase grid tied solar inverter’s simulation is being presented in this paper. Transformerless topologies improve the efficiency of the system. The inverter’s simulation model has been developed in Matlab/ Simulink. There are however issues such as the leakage current phenomenon that need further discussion. We analyze the parts of the model that are: the PV model we use, the MPPT algorithm through a DC/DC converter, the inverter’s control circuit, the LC filter, the connection to the grid and the passive filter. We also discuss the use of a Kalman filter in order to reduce the total harmonic distortion. The analysis and the results we extract, arise from a whole system simulation.
