Thyristor Working Principle
951.015
The resulting input voltage on the primary side of the Power Transformer generates a certain
output voltage (given by the voltage ration for the Power Transformer) to the series circuit.
This output voltage generates a current in the series circuit corresponding to the impedance in the
series circuit.
The current transformer measures the value of the current in the series circuit and the measuring
signal is send back to the CCR Module. In the CCR Module, the RMS value of the current is
calculated, and a control is performed to see whether the current have a value corresponding to the
requested value (our Reference Value). If that is not the case, the electronics will chance the time
for triggering the thyristors in each half wave until the current have the correct value.
