Funktionsweise
Functionality
The thyristor controller measures the displacement angle of the bridge output voltage using a digital phase-locked loop.
Firing pulses are generated for the connected thyristors based on the configured or recognized grid and the setting for the type of bridge.
The thyristors are fired by applying a grid-synchronous pulse pattern to the gate connectors. The type of pulse pattern, the control region, or the option for compensation of the control law are dependent on the grid configuration, the type of bridge, and the source for the set-points.
