Research output: Contribution to journalArticlepeer-review


A novcl type of invcrter is proposed for grid-connection of new energy power generation. The proposed inverter is based on buck-boost operation well-known in DC chopper circuits. This inverter acts as an interface between the generator and the grid and has a distinctive feature of realizing the inverse load flow with a wide range of input DC voltage. A control scherne of DC reactor current is also introduced in order to reduce losses in the DC reactor. The performance and characteristics of the proposed inverter is discussed in computer simulation.
