Direct power control of matrix converter based unified power flow controllers [PDF]

2009 35th Annual Conference of IEEE Industrial Electronics, 2009
This paper presents the Direct Power Control of Three-Phase Matrix Converters (DPC-MC) operating as Unified Power Flow Controllers (UPFC). Since matrix converters allow direct AC/AC power conversion without intermediate energy storage link, the resulting UPFC has reduced volume and cost, together with higher reliability.
