Abstract :
This paper proposes a new AC/AC converter topology which eliminates the need of back-to-back topologies in FACTS controllers that exchanges active power with the line. Unlike direct AC/AC converters, the proposed converter is based on the use of a network of variable impedances (either capacitive or inductive), which are implemented by converters acting as reactive compensation units. A bridge configuration can implement a fully controllable voltage source which is suited to control both the active and reactive power flow in a line. The principle of operation of this AC/AC bridge converter topology is explained in detail and a suitable control strategy for the control of the output voltage is developed. Experimental results from a low power prototype validate the proposals and demonstrate its effectiveness to control the flow of active and reactive power in a line.
