Efficient High Power Amplifiers with Transmission Power Control Function
29th European Microwave Conference, 1999, 1999A new switchless scheme of transmission power control (TPC) function for high power amplifiers (HPAs) is proposed. Ku-band amplifier MMICs that followed this scheme were fabricated and tested. The amplifier MMICs and transmission lines instead of switches were used to construct the HPAwhich has TPC function by switching two amplifiers.

Unified Power Flow Controllers for Security-Constrained Transmission Management
IEEE Transactions on Power Systems, 2004Although flexible ac transmission system (FACTS) devices and unified power flow controllers (UPFCs) have proven to be powerful tools for the exploitation of network capacities, their performances with regard to transient stability have not been deeply explored yet.

The unified power flow controller: a new approach to power transmission control
IEEE Transactions on Power Delivery, 1995This paper shows that the unified power flow controller (UPFC) is able to control both the transmitted real power and, independently, the reactive power flows at the sending- and the receiving-end of the transmission line. The unique capabilities of the UPFC in multiple line compensation are integrated into a generalized power flow controller that is ...

Global controllability of the power transmission network
Proceedings of 35th IEEE Conference on Decision and Control, 2002Global controllability of 2D and 4D nonlinear models of power transmission networks governed via flexible AC transmission systems (FACTS) is studied. This suggests that control functions enter the system via coefficients. The approach employed is based on a qualitative method.

Reducing Transmission Losses via Reactive Power Control
2021Modern smart grids are required to transport electricity along transmission lines from the renewable energy sources to the customer’s demand in an efficient manner. It is inevitable that power is lost along these lines due to active as well as reactive power flows.
