Abstract :
The distributed generation system using new energy sources has attracted much attention. Since this distributed generation system links to a commercial source, a utility interactive inverter is required. In this case, some different levels of DC voltage are applied as the input for the inverter because there are new energy sources such as solar batteries and fuel cells, and they provide different DC-voltage levels. We propose a double-bridge (DB) inverter that can operate for a wide range of DC input voltage. We have analyzed the operation mechanism of the DB inverter including the control system. The analysis has been confirmed by simulation
