Phase-fired control (PFC), also called phase cutting or phase-angle control, is a method for power limiting, applied to AC voltages. [1] It works by modulating a thyristor , SCR , triac , thyratron , or other such gated diode -like devices into and out of conduction at a predetermined phase angle of the applied waveform.
By linking the two sets of Power Electronics through a DC bus, typically by using GTO Thyristors or IGBTs, a TCPAR can be formed. While doing this may initially seem unnecessary, by looking at the shunt and series transformers and their electronics separately, it is apparent that the shunt portion is a STATCOM, and the series portion is a SSSC.
The thyristor also greatly improved the control system, allowing an SVC to detect and react to faults to better support the system. [8] The thyristor dominated the FACTs and HVDC world until the late 20th century, when the IGBT began to match its power ratings. [9]
The thyristor power controller switches 60% of the solid waves to the load while blocking 40%. The operating mode is to be regarded as unproblematic. Only in the case of a too weakly designed network, it is possible for illuminating installations which are connected to the same network to have undesired luminance fluctuations (flicker effect).
