摘要：
In this paper, a modified single-phase grid connected current source inverter is proposed for photovoltaic system application. The proposed converter is able to connect low voltage photovoltaic panels to grid without using transformer or extra dc-dc boost converter. Also, a current reference tracking based control method is proposed which tracks sinusoidal reference current and injects sinusoidal current to grid. So, the maximum power point can be tracked. To evaluate performance of the proposed topology, it has been modeled and simulated in PSCAD/EMTDC. The simulation results conform effectiveness and good performance of proposed converter.
