Abstract :
This paper presents a modeling technique, so called Power Oriented Graph, suitable for designing and simulating new topologies of inverter in energy generation system and reducing production cost. This technique is used for modeling a recently proposed soft-switching grid-connected DC/AC power converter for photovoltaic systems. Modifications in the structure of the DC/DC converter and in the control of the DC/AC converter are proposed. Simulation results confirm the effectiveness of the presented model and the introduced improvements.
