TELKOMNIKA Indonesian Journal of Electrical Engineering, 2012 Unified power flow controllers (UPFCs) are FACTS devices which can fulfil multiple power-flow control objectives, such as the need for reactive shunt compensation, phase shifting and series compensation. However, as they are quite expensive, they are not widely used.

Transformerless UPFC Using Multilevel Inverter
International Journal Of Engineering And Computer Science, 2017 This paper proposes transformer-less Unified Power Flow Controller (UPFC) which can be able to control the parameters of the transmission line. It incorporates back to back inverter that requires large transformers for power flow injection. The transformers are somewhat bulky, very costly and introduce high losses due to magnetic properties of the ...
