This is achieved by controlling the average value of load voltage using phase-control techniques. The circuit configuration is similar to the single-phase half-wave rectifier, the major change being that the diode is replaced by an SCR. A trigger circuit must also be included to control the SCR. Many variations of the trigger circuit are possible.
In this compensator, the equivalent value of the series connected reactor can be continuously controlled by adjusting the firing angle of the thyristors. As a consequence, this device presents a continuously controllable series capacitor. Various practical systems based on this concept are under operation around the world [13–15].
Where phase-control techniques are employed, only part of an AC wave is used. The thyristor devices block conduction until they are triggered into the on state. Triggering of the thyristor may occur at any time in a given half-cycle. The longer triggering is delayed, the lower the load voltage will be.
In the two- and four-quadrant modes of operation, power can flow from the dc side to the ac side, resulting in what is known as a phase-controlled inverter. It will be shown later that for the inversion process to take place, the dc side must contain a type of energy source capable of delivering energy from the dc circuit to the ac supply side.
The phase-controlled current and voltage waveforms are related by the delay angle, α. This is why α is also known as the angle of retard. Both the THD and the input power factor are reduced in the phase-controlled rectifier due to the presence of the displacement angle α.
