Thyristor power controller in a three-phase economy circuit

A The power controller produces the power that is needed at the analog input or in manual mode. Safety systems independent of the power controller must be installed. They should safely switch off the subsequent heating process in the event of excess temperatures. A The power controller may only be operated using original JUMO semiconduc-tor fuses.

TCSC (Detailed Model) - MATLAB Simulink

A TCSC is placed on a 500kV, long transmission line, to improve power transfer. Without the TCSC the power transfer is around 110MW, as seen during the first 0.5s of the simulation when the TCSC is bypassed. The TCSC consists of a fixed capacitor and a parallel Thyristor Controlled Reactor (TCR) in

SCR Thyristor Phase Control Circuit

The function of this circuit is to control the average value of power in a DC load supplied from an AC source. 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.
