Control Strategy for Power Flow Control
... The first function can be acheived "slowly", since thermal time constants are large. However, the last two functions require quick response capability which is possible since TCSC is power electronically controlled. We now consider control systems which will help us achieve these strategies. ...

Power inverter
A power inverter, or inverter, is an electronic device or circuitry that changes direct current (DC) to alternating current (AC).The input voltage, output voltage and frequency, and overall power handling depend on the design of the specific device or circuitry. The inverter does not produce any power; the power is provided by the DC source.A power inverter can be entirely electronic or may be a combination of mechanical effects (such as a rotary apparatus) and electronic circuitry.Static inverters do not use moving parts in the conversion process.
