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.

Robust Decentralized Control of Unified Power Flow Controller [PDF]
American Journal of Applied Sciences, 2009 A new approach based on structured singular value is proposed for the robust decentralized Unified Power Flow Controller (UPFC) design. To achieve decentralization, using the schauder fixed point theorem the synthesis and analysis of Multi-Input Multi-output (MIMO) control system is translated into set of equivalent Multi-Input Single-Output (MISO ...
